Question

Glycosylase scans the major and the minor groove and does what to check for error?

(A) Repairs DNA damage
(B) Removes damaged bases
(C) Initiates transcription
(D) Promotes translation

Answer 1

Glycosylase scans the major and minor groove of DNA to check for errors and removes damaged bases in the process.

Step-by-step explanation:

Glycosylase scans the major and minor groove of DNA to check for errors and removes damaged bases (B) as part of the DNA repair mechanism. Specifically, glycosylase catalyzes the hydrolysis of damaged bases from the DNA, which are then replaced by repair synthesis with DNA ligase. This repair process is known as base excision repair (BER) and is one of the several DNA repair pathways that exist.
