Semi-conservative replication: In semi-conservative replication, the double-stranded DNA molecule is unwound and each strand serves as a template for the synthesis of a new strand. As a result, each new DNA molecule formed consists of one original (old) strand and one newly synthesized strand.
Bidirectional replication: In bidirectional replication, the DNA molecule is unwound at a specific origin, and two replication forks are formed. Replication occurs in both directions, with one fork moving in the 3' to 5' direction and the other moving in the 5' to 3' direction. This allows for faster replication in organisms with large genomes.
Semi-continuous replication: Semi-continuous replication is a characteristic of DNA replication in which synthesis of one of the DNA strands, known as the leading strand, is continuous and occurs in the 5' to 3' direction. However, synthesis of the other DNA strand, known as the lagging strand, is discontinuous and occurs in short fragments called Okazaki fragments. The Okazaki fragments are later joined together by DNA ligase to form a continuous strand.
