Answer #1

Option D

DNA replication is the process by which DNA duplicates itself. It takes place in cytoplasm of prokaryotes and in nucleus of eukaryotes.

Many different enzymes are involved in this process.

The most important enzyme is DNA polymerases which polymerises DNA in 5' to 3' direction.

The direction and different enzymes involved in the process can be seen in the diagram given below -
