DNA Replication and Repair

DNA Replication and Repair

by Kevin Ahern, PhD

Deoxyribonucleic acid (DNA) is the cornerstone of biological systems. The codification of information in genetic sequences ensures the passing of traits to the next generation, after these have proven to contribute to survival via natural selection. During their stay in the nucleus, DNA polymers undergo damage due to myriad factors and are repaired by specific components of the cellular machinery. Before cell division, genetic information is replicated so that it may be inherited by the two daughter cells.

In this course, the student will be introduced to the basics principles and enzymes involved in DNA replication and repair. Telomeres will also be introduced and briefly discussed.

For optimal comprehension, the student will be required to be familiar with the basic notions of molecular and cellular biology and the biochemistry of nucleic acids.

Amazing
By Fatih Bedirhan Ç. on 05. November 2021 for DNA Replication and Repair

Short and simple. Right through to the significant things. Thanks to the professor.

 
Great summary
By Ana Z. on 16. September 2021 for Replication Fork

Wonderful, simple and easy-to-understand video. Finally got it

 
Too confusing
By Ana Z. on 16. September 2021 for DNA Repair

This video has several problems. It does not seem to be a continuation of the previous ones, it has unclear information, the reparation itself is not explained, and the name dropping doesn't help either.
