Question

what is the function of dna polymerase?
a breaks hydrogen bonds between dna strands
b joins nucleotides of the replicating dna strand
c joins amino acids to form a protein
d none apply.

Explanation:

• Option A: Helicase breaks hydrogen bonds between DNA strands, not DNA polymerase.
• Option B: DNA polymerase's function is to add (join) nucleotides to the growing replicating DNA strand during DNA replication.
• Option C: Ribosomes (with tRNA and mRNA) join amino acids to form proteins, not DNA polymerase.
• Option D: Since Option B is correct, D is incorrect.

Answer:

B. Joins nucleotides of the replicating DNA strand
