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 dissent
The most-upvoted critical review (3 votes, 2.0★).
“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.”
Coursera's 4.6 comes from 4,899 ratings. Of those, 1.6% are 1–2★.
Starisk reads the reviews learners voted most helpful, and weights each by the square root of its votes: a review with 80 upvotes counts about five times one with 2. Unvoted reviews are not skipped out of laziness — by this model they carry no evidence that other students endorsed them.
That measures what the most-endorsed reviews say, not “true quality.” The rating distribution above is the whole population, so you can see the sample next to it.
