Question

question 1
what keeps the two dna strands separate during replication?
single strand binding phosphates
single strand binding proteins
double strand binding proteins
double strand binding saprophytes

Explanation:

During DNA replication, helicase unwinds the double - helix, separating the two strands. Single - strand binding proteins (SSBs) then bind to the separated single - stranded DNA. Their role is to prevent the re - annealing (coming back together) of the two DNA strands. Phosphates are part of the DNA backbone structure and not involved in keeping strands separate. Double - strand binding proteins would bind to double - stranded DNA (not the separated single strands), and saprophytes are organisms that feed on dead organic matter and have no relation to DNA replication in this context.

Answer:

single strand binding proteins
