Which enzyme catalyzes the elongation of a dna strand in the 5' → 3' direction by adding nucleotides to the end of a growing dna strand? a. dna ligase b. primase c. dna polymerase d. topoisomerase e. helicase

DNA polymerase

Explanation:

DNA polymerase enzyme catalyses the reaction of adding nucleotide to growing complementary daughter strand of DNA in the direction of 5' → 3' during elongation in the process of replication. This process requires energy which is taken from nucleotides with three phosphate groups in their backbone similar to ATP (adenine triphosphate)

DNA Replication is when DNA multiplies and make exact copies of itself as part of gene transfer.

option a and d is the correct answer

i hope this u
