Number of dna molecules after s phase
WebS phase ( Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G 1 phase and G 2 phase. [1] Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved. Regulation [ edit] WebHuman somatic cells begin the cell cycle with each chromosome consisting of one DNA molecule. The DNA is replicated during S phase such that each chromosome consists …

These include DNA polymerases, single-strand DNA binding proteins, helicases, primase,topoisomerases, and DNA ligase.
WebAnswer (1 of 2): That’s a great question. I would like to explain this to you somewhat like this. there are two terms to remember, C and N. C is the DNA content and ... WebASK AN EXPERT. Science Biology A cell in G1 of interphase has 12 chromosomes (2 n = 12). How many chromosomes and DNA molecules will be found per cell when this original cell progresses to the following stages? a.

WebApigenin induces cell cycle arrest at different proliferation stages including G1/S-phase or G2/M phase by modulating the expression of different CDKs and other genes. It is known that apigenin can regulate intrinsic apoptotic pathways, changing mitochondrial membrane potential and causing the release of cytochrome C in the cytoplasm, which subsequently … WebInterphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, …
WebSolution Verified by Toppr Correct option is B) Second growth stage or G 2 stage occurs after the synthesis or S phase in which DNA replication occurs. Hence, the number of DNA molecules in each chromosome at G 2 stage will be two. So, the correct answer is option B. Solve any question of Cell Cycle And Cell Division with:- Patterns of problems >

Although the number of DNA molecules double between G1 and G2 of the cell cycle, the number of chromosomes remain the same. Chromosomes can be counted by counting the number of centromeres.
