Question

For the gene "umuD'2C" encoding DNA polymerase V (DNA pol 5), what is its function?

A) Repair of thymine dimers in DNA.
B) Initiation of DNA replication.
C) Proofreading during DNA synthesis.
D) Error-prone translesion synthesis during DNA repair.

Answer 1

The function of the gene 'umuD'2C' encoding DNA polymerase V (DNA pol 5) is error-prone translesion synthesis during DNA repair.

Step-by-step explanation:

The gene umuD'2C encodes for DNA polymerase V (DNA pol 5). The function of DNA polymerase V is D) Error-prone translesion synthesis during DNA repair. DNA polymerase V is involved in a process called translesion synthesis, which is a mechanism used to replicate damaged DNA when regular DNA polymerases cannot continue replication due to lesions or errors in the DNA template. DNA pol 5 is able to replicate past these lesions, allowing cells to bypass the damage and continue replication.
