Answer:
b
Step-by-step explanation:
The single-stranded regions of DNA are protected during replication by single-stranded binding proteins.
The single-stranded binding proteins are a class of protein found in some living organisms. They bind to single-stranded regions of the DNA during the process of replication, recombination, or DNA repair and protect the DNA from being degraded by nuclease enzymes. In addition to protecting the single-stranded DNAs, they also hinder the single-stranded DNA from premature hardening during replication.
The correct option is b.
