Mode of DNA replication: Meselson-Stahl experiment

WebThis is the main replicating enzymes in prokaryotes which is mainly responsible for the synthesis of new DNA strands (5′ to 3′ polymerase activity) by bringing in new nucleotides. It is composed of a complex structure with alpha, epsilon and theta subunits in its core. These 3 subunits are responsible for following main functions: DNA ... WebThe origin of replication is recognized by certain proteins that bind to this site. An enzyme called helicase unwinds the DNA by breaking the hydrogen bonds between the nitrogenous base pairs. ATP hydrolysis is required for this process. As the DNA opens up, Y-shaped structures called replication forks are formed.
