DNA Replication and Checkpoint Control in S Phase

WebInterphase is a preliminary phase that is separated into three parts: Gap1 (G1), Synthesis (S), and Gap2 (G2). True cell division occurs during the M phase of mitosis. S phase : The replication phase is known as the S phase. DNA replication consumes the majority of the cell's resources. All 46 chromosomes are duplicated in human cells. WebDNA replication in a bacterium during the log phase happens continuously. This is a fundamental supposition dependent on the accompanying four basic facts: The genome of E. coli is about 4.5 Million base pairs long. The speed of Replication is around 1000 bases/sec. Replication takes 15 min to complete.
