G₁ cells are larger and more likely to perform the normal functions of the cell. B. G₁ cells have not replicated their DNA in preparation for division. C. G₁ cells are the only ones that do not have their chromatin in a highly condensed state. D. MPF is required to enter S phase, so the cell is committed to entering M phase if the cycle moves beyond G₁. How many does the chromosome number of the species A.

If the situation in part a occurred, would the new cells be viable? Explain. no, it wouldnt have the DNA OP 10. The S phase stands for synthesis, which means to make or build something more complex out of simpler parts. Scientists know that during the S phase DNA is being made in the nucleus of the cell. Why do you think the cell needs to make more DNA at this time in the cell cycle? 11. Refer to Model 1. The chromosomes that are shaped like "X" (made of two sister chromatids) have double the amount of DNA than the chromosomes that are shaped like "I." During what phase of the cell cycle do you think the chromosomes are replicated (copied)? POGIL Activities for High School Biology 2. hparrow_forwardSometimes a cells "deal with" damaged DNA by just killing off the cell. This special cellular suicide is called apoptosis. Usually, the cell cycle has checkpoints that prevent damaged/mutated cells from proceeding to the next phase, though. When these checkpoints don't work, apoptosis can be used. If apoptosis did NOT occur, how might the damaged DNA impact the rest of the cell cycle? A. it may not complete the cell cycle correctly B. new cells containing damaged DNA may be made C. the cell may enter G0 D. all of the above are options E. A and B, but not C F.
