About the Course

This course introduces you to the basic biology of modern genomics and the experimental tools that we use to measure it. We'll introduce the Central Dogma of Molecular Biology and cover how next-generation sequencing can be used to measure DNA, RNA, and epigenetic patterns. You'll also get an introduction to the key concepts in computing and data science that you'll need to understand how data from next-generation sequencing experiments are generated and analyzed. This is the first course in the Genomic Data Science Specialization....

It was well taught. I liked the fact the two professors focused on two different subjects- biology and statistics portion of this course. The paragraphs written below each video was extremely helpful.

Great introduction to Genomics. The instructors really laid out the practical terms and gave great resources. Weeks 3 and 4 ramp up in difficulty, so some outside research in statistics is helpful.

The information is good, but they really don't highlight what they think will be important to remember in general, or specifically for the quiz. In particular, there are a couple of videos that say something like "you don't have to memorize this", but then it shows up as a question on the quiz. If you didn't memorize it, you may have issues.

I am a PhD student in genetics, so the background material there was review from undergrad courses. Obviously some people who are not biologists will need this background. I do wish, however, that the statistics intro was more applied and covered a better intro and application to the why!

too easy, some part of statistic not very clear, but maybe becouse this is a beginner course, I will do rest of the course.

The stats section in week 4 sucked. The rest was spot on.

Basic course

I didn't like much this course because teacher speaks so fast (I always had to stop and watch again) and classes are so long. I'm not a native english speaker and, beyond his high speech speed, I had difficulties to understand him sometimes because some of his sentences are truncated (he starts to say something in a sentence and he changes it by the way, turning it into a difficult sentence to foreign people understand).

This course if just a quick fly-by overview. You don't learn anything relevant in biologiy, computer science or statistics. Some questions in the quiz were not part of the course which is really annoying. Anyhow, I like the idea of reading a paper as an academic part of this course.

-poor material, no usage of assistant technologies

-hasty teacher

-bad exams, exams very playing with the wording and not with the understanding

Brief Profile: Sohail Butt

I am a man of 58 years old and having an experience of almost 30 years of Business Management of Pharmaceutical & Nutraceutical Industries of Pakistan. Presently I am having my own Consulting Company " AIMMS CONSULTING" and extending my services as Management Consultant to different companies of said sectors.

I am of the conviction that learning is never ending and have a habit of learning new ideas about my favorite subject about Data Science. Although I have the limited usage of this subject in my working areas but I love to know about new areas of different specialties.

I really appreciate highly the efforts of Prof Steven Salzberg, PhD & Sssociate Prof Jeff Leek, PhD and enjoyed the course material and videos presentation of this course. Mind blowing approach was adopted especially in the conceptual background with extremely useful Bioinformatics, Computational and statistics in the course of Introduction to Genomic Technologies.


MY PERSONAL HUMBLE REQUEST, Please make also the important components of course material as a part of this Certificate with % AGGREGATE so that it has a much more worth & impact for the courses participated.

A separate Transcript must be issued with having Aggregate % Score and important Components of participated course.

Hard Copy of this certificate mail to my home address in Pakistan. Please use my credit card,I am ready to pay all expenses in this connection.

Thanks & best wishes to all Coursera Team.

I highly recommend this course for everybody who has literally no biological background and would like to learn something about Molecular Biology and Genomics.

I have tried to learn a little bit by myself a few times in my life but for every try I ended up with some endless clicking at next and next definition from wikipedia, not knowing what is crucial and what I can skip to get a general idea about the subject. Everything but not a successful way of learning. Here, they give you the essence in an understandable way, together with some of these "interesting funny facts" from the field that, added to a lecture, make you more willing to stay focused.

This course have helped me get ready for the next step in my career. It has helped me understand what is going on in the laboratory that I am working at. It is a good course for me because we are planning to put up a molecular biology laboratory in my Department. It has helped me conceptualize what are the things that we will need. The course made it easier to understand with the visual presentations even though I am not familiar with bioinformatics. Ideally we will be doing sequencing as well on our research and it is a good thing that the course introduced new technologies as well that are cheaper and more efficient options. ThankshnThankThank

This course introduces you to modern genomic technologies, some statistics and the importance of computational biology. I think anyone taking the course could understand how understanding the basics of statistics, genetics, molecular biology and even some programming could help them if they are serious about Genomic Data Science. But that's it. You could become confused and overwhelmed if you have no real understanding of any of these subjects. The fact that this is just an introduction to the 8 part specialization would escape your mind if you feel overwhelmed.

This is from an AS Level student with relatively low knowledge about Genome and the technology regarding it, this course was perfect for beginners who wish to just learn. The basics were explained and at times acknowledged. But, after this course, I'm definitely determined to proceed in this specialization.

The instructors are proficient, well-spoken, and did an amazing job at explaining and the quizzes were definitely well-constructed. I loved learning about Genetics not just in terms of biology but through a computational and statistical perspective.

It was a very good introduction to the genomics field!

Great professors and efficient assignments. Generally i enjoyed the course, but had two difficult points:

1) the 4th week was harsh because very broad subjects were given only for a few minutes and werent deeply explained (there werent enough examples or calculation exercises)

2) the final project was hard and merely connected to the course's material in my opinion. there were a lot of terms that were not mentioned in class.

A good, very brief, overview of genomic data science covering basic molecular biology, techniques, CS and statistics. The quizzes are not difficult and the end project is quite interesting. Would appreciate explanations of the correct answers after getting our scores. You do need to have a bit of a background in high school / introductory college classes on these topics, especially for the biology part as the lectures go pretty fast. Overall a good overview.

I've learned many new things. Coming from the CS / Data Science background, this was a great introduction to biology side of genomics.

I'd also recommend to all students in this class an excellent book on the history of genetics and genomic research that was recommended in my Data Science course at Indiana University: "The Gene" by Sidhartha Muherjee. The book is non-technical, but gives a great background knowledge and motivation for further study.

This is a great course that covers a lot of ground very quickly, including an overview of the central dogma of biology, mitosis and meiosis, and basic concepts in computer science and statistics. The lessons are clear, understandable, move at a good pace, and are full of practical examples applying concepts to actual problems in genomic data science. This class was a great starting point for the specialization and I highly recommend it.

this was good course. Its really appreciating that you are teaching students sitting at home and learning online. this course was also good but i feel difficulty in learning 4th week course. Especially calculating p value and plotting data . I think that should be more precisely and should be describe with more examples. Thank you so much for this course and for increasing my knowledge.
