Dna replication what phase
WebCells respond to DNA damage or incompletely replicated chromosomes in G2 phase by delaying the G2/M transition so as to prevent attempts to segregate damaged chromosomes. DNA damage is detected by the kinases ATM and ATR, which activate Chk1, an inhibitory kinase of Cdc25. WebDNA replication is required for cell growth, repair, and reproduction in all living species. Stages of DNA replication DNA replication is divided into three stages: initiation, elongation, and termination. Initiation DNA synthesis begins at specified locations along the DNA strand known as ‘origins,’ which include specific coding sequences.
