Question

which of the following molecule(s) help(s) to hold the dna strands apart while they are being replicated?
ligase
single - strand binding proteins
primase
dna polymerase

Explanation:

Ligase is responsible for joining DNA fragments. Primase synthesizes RNA primers. DNA polymerase adds nucleotides to the growing DNA strand. Single - strand binding proteins (SSBs) specifically bind to the separated DNA strands to prevent them from re - annealing (coming back together), thus holding them apart during replication.

Answer:

Single - strand binding proteins
