D)transcription.
E)base matching.

Question

Quizplus · Accepted Answer

Complementary base pairing between the nucleotides is what allows for accurate duplication of the DNA sequence. The nucleotides always pair up in a specific way (A with T, and C with G) which ensures that the correct sequence is maintained during replication. Polymerase and other enzymes are involved in the process, but it is the complementary base pairing that is the key mechanism for maintaining the accuracy of DNA duplication. Transcription, on the other hand, involves the transfer of genetic information from DNA to RNA and is not directly related to DNA duplication.
