DNA polymerase adds nucleotide to the ____ end of the primer
|
|
3’
|
|
|
5’
|
Explanation:
Detailed explanation-1: -DNA Polymerase Only Moves in One Direction After a primer is synthesized on a strand of DNA and the DNA strands unwind, synthesis and elongation can proceed in only one direction. As previously mentioned, DNA polymerase can only add to the 3’ end, so the 5’ end of the primer remains unaltered.
Detailed explanation-2: -Primase synthesizes RNA primers complementary to the DNA strand. DNA polymerase starts adding nucleotides to the 3’-OH end of the primer.
Detailed explanation-3: -DNA polymerase adds nucleotides to the 3’ end of a primer, extending the new chain in a 5’
