À propos du cours

Named a top 50 MOOC of all time by Class Central! This course begins a series of classes illustrating the power of computing in modern biology. Please join us on the frontier of bioinformatics to look for hidden messages in DNA without ever needing to put on a lab coat. In the first half of the course, we investigate DNA replication, and ask the question, where in the genome does DNA replication begin? We will see that we can answer this question for many bacteria using only some straightforward algorithms to look for hidden messages in the genome. In the second half of the course, we examine a different biological question, when we ask which DNA patterns play the role of molecular clocks. The cells in your body manage to maintain a circadian rhythm, but how is this achieved on the level of DNA? Once again, we will see that by knowing which hidden messages to look for, we can start to understand the amazingly complex language of DNA. Perhaps surprisingly, we will apply randomized algorithms, which roll dice and flip coins in order to solve problems. Finally, you will get your hands dirty and apply existing software tools to find recurring biological motifs within genes that are responsible for helping Mycobacterium tuberculosis go "dormant" within a host for many years before causing an active infection....

This course is very very good. Challenging at times. It does not hold your hand at all times and sometimes requires research to solve some of the problems, but I like the community and the approach.

Excellent introduction to bioinformatics. They put a lot of heart and thought into the design of the course. I will continue to use the concepts I've learned in and out of bioinformatics.

I have received financial aid because I was interested in the bioinformatics field and was reading alot about it and wanted to start my first course, it was my biggest mistake that I have chosen this course. It is awfully explained, terrible accent, basically a course with 50% information for beginners and 50% for coders and the quiz for week 2 just pumped my blood pressure to the roof, this course is in no way to be called for beginners and the interactive text is a mess and it is no way as a biotechnologist that I am going to recommend this course to anyone !, I need to apologize for coursera company for giving me aid for this COURSE !

note : this course is basically like a money grab, it is not enough that you are on their course they actually from Minute one advertise for their book vol 1 and 2... such a joke.

All in all I am stopping this course because the knowledge I am gaining from this course is 1 on the scale of 10, and the amount of confusion and frustration and disappointment I am getting is 10 on the scale of 10 !!

I really hope coursera can forgive my dropping out of this course and allows me to get a financial aid at an actual course

This course is really frustrating if you are not a computer scientist.

The 'language-neutral pseudocode' given on the computer science tasks is buggy and hard to figure out and there is no support or solutions. This course is just hours spent rerunning your code by brute force to pray you get to their answer to pass.

Work is not explained well. The only reason to take this course is that its supported by UCSD.

Very tough but rewarding class. The programming part was easy, the algorithms kicked my butt. Love the challenge and can't wait to take the rest!!! Such an interesting field!

Unfortunately, as often happens, what is "simple" and basic for one is not that for another. This course presumes a comfortableness with coding that I simply do not possess as a teacher of high school science. Please try and develop a true introductory course that normal, non-programmers can access. Thanks!

Excellent course. The Stepik grading could use a couple of tweaks and perhaps a bit more debugging, but it was an excellent blend of bioinformatics, molecular biology, and programming.

I applied for financial aid to take this course because it was supposed to be an introduction to bioinformatics that doesn't require coding. I was wrong, after struggling almost a month I have been unable to get past week 2 because the assignments require coding skills. I am going to have to unenroll and I am so pained by this because I try to finish all the courses I get financial aid for. If you are a biologist with no coding knowledge I do not recommend that you take this course.

Videos and content are unrelated. Stepik application doesn't accept our answers even if it is true!

As others have pointed out, this course is not for beginners at all, in both biological or computer science (CS) sense. For example, this course assumes students have good knowledge of string manipulation (which many biological students don't) or good knowledge of genetic basics (which many CS students don't). Especially for biological students, some algorithm implementations (in the interactive platform -- stepik) could be very frustrating like recursive calls. The professors do not explain these concepts and keep saying something like "it's Ok you don't know this you don't know that" which I found is not helpful and actually distracting.

That said, I still rate this course 5 stars, as I'm not a beginner in both senses and found the contents very appealing. I'm actually very familiar with all the biological materials the professor offered; however, I found myself know much more and deeper than before as I understood the algorithms and did some programming practice. I'm convinced that the materials are well chosen that we can benefit from switching perspectives between biology and CS. The contents are also built up in a clear path such that the learning curve is smooth (under the circumstances that you are not a beginner).

Using the interactive learning platform is an absolutely gorgeous experience; I'm super-satisfied not only because of the easily accessible format but also the comments from other students make the course lively and engaging.

This course is wonderful. It helps me to learn bioinformatics systematically and make my python coding ability stronger. This videos and coding challenges are quite informative, it covers a lot of materials that I could study. This course not only enriched my knowledge on bioinformatics but also extend my views on biology that some questions I never thought deeply before. So, from learning this course, I also mastered some of my understanding about biology questions. Thanks for all the teachers and instructors’ endeavor to make this course fantastic. The only thing I want to suggest is that some Pseudocode is hard to understand. For finishing the coding challenge, I also checked information from Google. I would like to say that if the teachers provide more clues for beginners, it would be amazing. All in all, thank you so much for the effort for this course.

This course was fun and very rewarding, I feel like I learned a lot about both algorithms and biology.

I have completed the Honors track---coming from a computer science background the algorithmic parts were mostly easy for me (I generally came up with all the algorithms on my own) but still fun to work through, especially because of their connection to real-world biology problems.

Interesting as the biological motivations had been they really only scratched the surface and made me want to learn more. For that I worked through the online MIT biology course [1] led by Eric Lander (of the Human Genome Project fame) that I cannot recommend enough.

Very well explained. I'm a molecular biologist seeking for some programming skills and understanding of the basics of the everydays tools. I've found some caveats in the coding problems from stepik but I understand that's difficult to give complete and exact explanations to everyone and every programming language that someone can use. Besides that everything's perfect! And recommended!

This course is really educational and well designed. The course content is well structured and clearly described. If you have no previous knowledge in this topic, I would recommend to start with the beginner's course "Biology Meets Programming: Bioinformatics for Beginners" in order to be prepared for concepts like pseudocode or the computational way of thinking in general.

Definitely recommended!

It is a great course that helps me by first simplifying the problem to the level that it becomes ridiculous and then solve that problem, then try to approach a problem with real world constraints using that ridiculous problem. It is a course that introduced me to some of the amazing information and principles that runs this world.

The material of the course is simply exquisitely presented. The concepts are clear, easy to grasp. You won't be a bioinformatician after doing this course, but you'll make the first step.

Take this course only if you are doing honors track, I cannot think of anything that you can learn from this course if you do not involve and improve your programming skills by applying them to the topics.

Videos were not very helpful, interactive texts were more informative. However interactive texts could not be understood in its totality were it not for the charitable efforts of few students to explain and clear out any inconsistencies in the discussion forms. Staff was not involved in these discussion forms and some of the obvious bugs and lack of explanations were not improved and fixed despite being mentioned multiple times during more than 5 years of the courses existence.

Lastly, they requested me to review/mark others students assignments in the last week in order for me to complete the course? That did not appeal to me very much since this course is paid.

This course could offer much more if they tried to improve it consistently overtime and pay attention to the reviews they get from students in discussion forms.

Very misleading and frustrating course. They said you don't need knowledge in programming for this "beginner" course but I find that untrue. This course is very difficult to follow for someone like me who doesn't know how to code. The pseudocode and the Stepik is even more confusing. The lectures are of no help. They barely explain anything and is very disengaging. The lecturer's accent is too thick to be able to discern. Maybe add subtitles? And then you have these quiz questions that seem to come out of nowhere. This course would probably be perfect for mid to high level programmers. Maybe change the course's difficulty level from "beginner" into "intermediate"? I wish I didn't waste my time with this course.

par Andres B

The pseudocode that describes most of the algorithms shown in this course is very poor and misleading.

I honestly dislike the format of the project at the end of the course. I am paying for this course, and thus I do not have to be the teacher (evaluating other's people project) and I must be evaluated by a someone who really has knowledge of the topic and not by other students like me.

i am very disappointed with this course, I will not recommend it and i am not sure if I am finishing it. You should learn form the courses of Andrew Ng.

Best regards.

The course was very well designed to engage any one with CS background to get highly motivated to learning Bioinformatics. Personally, I have found the humorous representations of the instructors very appealing and also enjoyed the programming challenges. Moreover, it helped me to develop an insight to connect my CS knowledge for solving Biological problems. I am looking forward to completing the full specialization.

Well made introduction into the field. Good programming exercises which are easy to medium difficulty with a computer science background. It feels like they put a lot of thought into the course structure. Some of the biological explanations are too brief without a biological background, and I would guess the same for students without a computer science background regarding the exercises.
