About The Course
The other type of mutation is extremely rare and can cause dramatic effects on the scale of species evolution. In genome rearrangements, huge blocks of DNA are heaved around, often from one chromosome to another. These mutations are comparable to earthquakes, which hoist up mountains and wrench apart continents.
When we compare two relatively short pieces of DNA that have not been affected by genome rearrangements (say, two genes taken from individuals from the same species), our goal is to identify a "path of least resistance" connecting these two genes via point mutations. We can find such a path using a powerful algorithmic paradigm called dynamic programming.
On the other hand, when we zoom out to the compare entire genomes taken from different species that diverged millions of years ago (such as humans and mice), the effects of genome rearrangements become more pronounced. To determine how far diverged these genomes are, we will need completely different combinatorial algorithms that will help us answer questions about the patterns of genome rearrangements. For example, in order to move around large blocks of DNA, a genome rearrangement must "break" the genome in at least two places. We know that there are fault lines on the earth's surface where earthquakes are more likely; are there analogous "fragile regions" in the human genome where breakage has been more likely to occur during a genome rearrangement?
Frequently Asked Questions
Yes. Students who successfully complete the class will receive a statement of accomplishment signed by the instructor.Q: Can I receive a verified certificate for this course?
Yes. Students who would like a verified certificate can sign up for the course's Signature Track option.
Q: I remember this course used to be part of the larger "Bioinformatics Algorithms (Part 1) course. Why was it split into three courses?
Based on survey feedback, completion data, and studies of other courses, we realized that having shorter courses gives our students more flexibility around their busy schedules. Even though the courses have been split, the overall content remains the same, so we feel confident that we're maintaining learning standards of our material.
Q: What if I earned a voucher for retaking the old course? Can I use it in this course?
Vouchers from the older course will be valid for the newer courses. If you took the original course and earned a voucher, you will be issued a voucher for this course as well as for "Finding Hidden Messages in DNA" and "Assembling Genomes and Sequencing Antibiotics" (three vouchers total).
Q: Does this mean that the overall cost for earning Verified Certificates in the course is greater now?
Yes. Since there are more courses now, the overall cost for Verified Certificates is greater than before. Coursera offers a Financial Aid program for learners who would face a serious hardship paying for our courses. Plus, if you just want to join and check out our course content, it's still free and available to everyone.
The programming assignments in this class can be solved using any programming language.
