Other Replication Proteins
About the Lecture
The lecture Other Replication Proteins by Kevin Ahern, PhD is from the course DNA Replication and Repair.
Included Quiz Questions
Which of the following is true of helicase in E. coli?
- It operates by unwinding the DNA strand
- It is found behind the DNA polymerase
- It assists in the re-winding of DNA after the replication fork passes
- It helps in the formation of base pairs
What is the role of SSB proteins?
- They help maintain the integrity of the ssDNA so that it does not break.
- They open the double-stranded form of DNA to single strands.
- They uncoil the DNA helix for replication.
- They help in the recoiling of newly synthesized DNA around the parental strand to recreate the duplex form.
- They help the DNA polymerase during the proofreading after the completion of replication.
Which of the following functions are NOT linked to DNA polymerase-I? (Select all that apply).
- To maintain the integrity of ssDNA during replication
- Stabilization of the replication fork structure during the replication process
- Proofreading of the newly synthesized DNA strand
- Replication of DNA in E. coli bacterium
- Removal of RNA primers during the replication process
Which of the following is NOT correctly related to DNA replication?
- SSB proteins — help in the synthesis of RNA primer during replication
- DNA pol I — 3’-5’ exonuclease activity
- Helicase — conversion of dsDNA into single-stranded form
- Topoisomerase Type 1 — relax the positively or negatively supercoiled DNA
- DNA gyrase — introduce negative supercoils into DNA by using ATP

this presentation was good and the way sir explained the concepts was nice
