WebSep 15, 2024 · The rolling circle mechanism is not limited to single-stranded DNA synthesis. This technique is utilised by certain phages (e.g., λ) to replicate double-stranded DNA. During the initial step of λ DNA replication, the phage replicates using the θ mode to produce multiple copies of circular DNA.

WebDuring lytic development of bacteriophage lambda, its genome is replicated according to the theta (circle-to-circle) mode early after infection, and then it is switched to the sigma (rolling circle) mode. Two mechanisms of regulation of this switch were proposed recently and both suggested a crucial role for directionality of lambda DNA ...

WebIn this article we will discuss about the theta structure of DNA, explained with the help of suitable diagrams. It is a structure formed in replication of circular DNA. Since this structure resembles the Greek letter θ it is known as the theta structure. Semiconservative mode of DNA replication in bacterial chromosome begins at the origin of ... WebHost enzymes, notably DNA polymerase alpha-primase, DNA ligase I, and topoisomerase II, are probably also required.
