Which of the following activity is not possible in the case of DNA polymerase I?

Which of the following activity is not possible in the case of DNA polymerase I? Correct Answer 3’-5’ DNA synthesis

DNA polymerase is having the ability to synthesize DNA strand in 5’-3’ direction but not in 3’-5’ direction. Also, it is having exonuclease activity in both the directions, which means that it can remove bases in either of the direction but can synthesize only in 5’-3’ direction.

Consider the following statements regarding DNA replication and choose the correct answer:
1. The very first requirement of DNA synthesis is the presence of a template or plan along which the new strand is to be constructed
2. The second requirement is of a DNA-dependent-DNA polymerase or simply DNA polymerase enzyme
