During DNA replication,
A)tRNAs bring specific amino acids to an mRNA molecule.
B)two single strands of DNA come together, restoring complementary base pairing.
C)amino acids are joined.
D)the DNA double helix comes apart, and new nucleotides are brought in, forming two double helices.

Question

Quizplus · Accepted Answer

During DNA replication, the double helix of DNA unwinds and separates into two single strands. New nucleotides are then added to each single strand, with complementary base pairing, forming two new double helices. This results in the duplication of the original DNA molecule. Choice A is incorrect because tRNAs are involved in protein synthesis, not DNA replication. Choice B is incorrect because it describes the process of base pairing during DNA repair, not replication. Choice C is incorrect because amino acids are involved in protein synthesis, not DNA replication.
