Final answer:
Rolling Circle Replication is the type of replication that occurs in circular DNA and involves only one replication bubble. It proceeds in either a unidirectional or bidirectional manner.
Step-by-step explanation:
Rolling Circle Replication is the type of replication that occurs in circular DNA. It proceeds in either a unidirectional or bidirectional manner and typically involves only one replication bubble.
In rolling circle replication, the process begins with the enzymatic nicking of one strand of the double-stranded circular molecule at the double-stranded origin (dso) site. DNA polymerase III then binds to the 3'-OH group of the nicked strand and unidirectionally replicates the DNA, using the un-nicked strand as a template. This process displaces the nicked strand and results in the full displacement of the nicked strand.
RNA primase synthesizes a primer to initiate DNA replication at the single-stranded origin (sso) site of the single-stranded DNA (ssDNA) molecule, resulting in a double-stranded DNA (dsDNA) molecule identical to the other circular DNA molecule.
