Web3. what errors can occur during mitosis and what are the implication to the living organisms? Answer: Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, ... You can avoid many of these errors by keeping good records and reducing the amount of manual work your team performs with automation. WebThe general answer is that internal and external cues trigger signaling pathways inside the cell that activate, or inactivate, a set of core proteins that move the cell cycle forward. You can learn more about these proteins, and see examples of how they are affected by cues such as DNA damage, in the article on cell cycle regulators.
