Eukaryotic Replication – DNA Structure and Replication
About the Lecture
The lecture Eukaryotic Replication – DNA Structure and Replication by Georgina Cornwall, PhD is from the course Understanding Genetics.
Included Quiz Questions
Which of the following best describes telomeres?
- Long, repeating sequences at the ends of chromosomes that protect the coding regions from damage
- Short RNA sequences that provide an attachment point for Okazaki fragments
- A short region of DNA where transcription begins
- A portion of the gene that is spliced out before transcription
- The terminal end of tRNA where amino acids attach
Which of the following best describes the function of telomerase?
- Decreases the rate at which telomeres shorten throughout a eukaryote's life
- Repairs breaks in the coding region of DNA
- Bonds Okazaki fragments together
- Prevents the upstream supercoiling of DNA during replication
- Unwinds DNA at the replication fork
Aging and cancer are associated with which of the following?
- Telomeric shortening
- A decreasing number of replication forks during replication
- An increasing number of Okazaki fragments
- The lengthening of centromeres
