Verified
In replication, once the DNA strands have been separated, reformation of the double helix is prevented by
A) DNA helicase enzyme.
B) single-strand binding proteins.
C) DNA polymerases.
D) ATP.
E) DNA primase.
Single-Strand Binding Proteins
Proteins that bind to single-stranded DNA during replication or repair processes, stabilizing the DNA.
DNA Primase
Enzyme that begins the process of DNA replication by synthesizing a short RNA segment complementary to the DNA template strand; this RNA strand is subsequently degraded and replaced with DNA.
ATP
For metabolism within cells, adenosine triphosphate acts as the vital molecule carrying energy.

Final Answer :
B
Explanation :
Single-strand binding proteins (SSBs) bind to the separated DNA strands during replication to prevent them from re-annealing or forming secondary structures, thus ensuring that the strands remain available as templates for replication.
