In G1, each chromosome is a single chromatid. WebApr 8, 2024 · DNA synthesis occurs during interphase. Complete step-by-step answer: The cell cycle of animal cells has two main stages: the Interphase and M phase. Interphase is the preparatory phase that is further divided into Gap1 (G1) phase, Synthesis (S) phase, and Gap2 (G2) phase. M phase is the mitotic phase where true cell division occurs.

Weba. chromosomes do not replicate during the interphase preceding meiosis I. b. chromosomes do not replicate between meiosis I and II. c. half of the chromosomes from each gamete are lost during fertilization. d. sister chromatids separate during anaphase of meiosis I. e. chromosome arms are lost during crossing over. 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] germeys rohnnyWebS phase. DNA replication occurs during S phase. Each chromosome is duplicated and thereafter consists of two sister chromatids (the products of DNA replication).
