DNA replication by DNA polymerase occurs in the ____ direction on the template strand.
A) 5'$\rarr$3'
B) 3'$\rarr$5'
C) both ways
D) none of these

Question

Quizplus · Accepted Answer

DNA polymerase can only add nucleotides in the 5' to 3' direction, so it can only replicate the template strand in the 3' to 5' direction. This creates a newly synthesized strand in the 5' to 3' direction, which is antiparallel to the template strand. Therefore, DNA replication occurs in the 3' to 5' direction on the template strand.
