- S. Chromosomes are duplicated during what stage of the cell cycle? G1 phase S phase prophase prometaphaseMatch the process with the correct phase of the cell cycle (G1, S, G2, M). If the process occurs in M phase indicate subphase (ex. telophase). E) ___________________Extra cell membrane is synthesized by the smooth ER. F) ___________________DNA is compacted into chromatin.Which subunits activate CDKs at different cellcycle stages. Cyclins are present only in the cell cycle stagesthat they promote.
- BPA is a chemical compound that has historically been used in themanufacture of plastic products. However, cells often mistake BPAcompounds for hormones that accelerate the cell cycle. Because ofthis, BPA is associated with an increased risk of certain cancers. Question: How might BPA interact with the cell cycle and its checkpoints?in term of signal transduction how cell cycle/division is controlled?? ((while you are answerig plz write the refrence.))Which of the following may contribute to pause the cell cycle? a) ATM b) ATR c) p27 d) all of these e) none of these f) a and b only .
