Origin of Replication
|
Detailed explanation-1: -DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis.
Detailed explanation-2: -The Replication Fork and the Replisome. The site of ongoing DNA synthesis during DNA replication is called replication fork. It comprises the two parental DNA strands that are separated in order to allow copying of each single strand by the DNA polymerases.
Detailed explanation-3: -An origin of replication is a sequence of DNA at which replication is initiated on a chromosome, plasmid or virus. For small DNAs, including bacterial plasmids and small viruses, a single origin is sufficient.
