Introduction:
In cell cycle, a mother cell divides into two daughter cells. The cell cycle mechanism is divided into four stages G1, S, G2, and M. G1, first gap phase within interphase, is also known as growth phase. During the G1 phase, cell synthesizes proteins and produces more number of mitochondria and ribosomes and increases their size of growth. In the G1 phase, cell synthesizes and accumulates materials needed for
DNA is a genetic material consisting of a long stretch of

- in which of the phases of the cell cycle do sister chromatids form? -g2 phase of interphase -g1 phase of interphase -m phase (mitosis) -s phase of interphase -c phase (cytokinesis)arrow_forwardPhases of the cell cycle (Mitosis) Interphase DNA, in the form of chromatin, replicates. Nucleolus is present, but may not be visible. Nucleus is clearly visible.arrow_forwardDuring cell division, centromeres have separated, and chromatids are pulled apart, becoming chromosomes. What happens after the chromosomes are pulled to opposite ends of the cell? Top of Form Prophase Anaphase Metaphasearrow_forward
