24-3 Replication of DNA Replication n An enzyme-catalyzed process 1.Begins with a partial unwinding of the double helix 2.Bases become exposed 3.New nucleotides line up on each strand in a complementary manner(A with T and C with G) 4.Two new strands begin to grow Each new strand is complementary to its old template strand 5.Two identical DNA helices are produced The process is described as semiconservative replication because each of the new DNA molecules contains one old strand and one new strand Replication ▪ An enzyme-catalyzed process 1.
