MCQ on DNA Replication

DNA replication is the process by which a cell duplicates its DNA before cell division. It involves unwinding the double helix, complementary base pairing, and enzyme-mediated synthesis of new strands, ensuring genetic continuity and transmission of genetic information to daughter cells. This is an MCQ on DNA Replication in Prokaryotes and Eukaryotes.
