  5. Replication fork Origin of replication ThetaReplication in Prokaryotes Termination of replication

  6. Linear Replication in Eukaryotes

  7. . The parent molecule has two complementary strands of DNA. Each base is paired by hydrogen bonding with its specific partner, A with T and G with C.

  8. . The first step in replication is separation of the two DNA strands. The parent molecule has two complementary strands of DNA. Each base is paired by hydrogen bonding with its specific partner, A with T and G with C.

  9. Semi Conservative process of DNA Replication The first step in replication is separation of the two DNA strands. Each parental strand now serves as a template that determines the order of nucleotides along a new, complementary strand. The parent molecule has two complementary strands of DNA. Each base is paired by hydrogen bonding with its specific partner, A with T and G with C.
