- Certain diseases are transmitted via mitochondrial DNA. Which cell types do you think would be most affected by such diseases, and why?arrow_forwardIn mitosis, why do the chromosomes need to condense in prophase and line up in metaphase? (To be clear, this is asking about the usefulness of these specific actions, not just that those things need to happen as part of the overall process.)arrow_forwardIn which of the three phases of interphase and the stages of mitosis dochromosomes exist as single DNA molecules?arrow_forward
- Some cells in organisms can divide on a daily basis while others do not divide as often. Which phase of the mitosis do you think would vary the most due to different rates of cell division and why?arrow_forwardDuring mitosis, a single cell divides to produce two daughter cells. What must happen in the original cell so that each of the daughter cells has a complete set of chromosomes?arrow_forwardYOU DON'T NEED TO EXPLAIN THESE QUESTIONS JUST PROVIDE ANSWER DNA separates during ____ of mitosis. a)Prophase b)Telophase c)Metaphase d)Interphase e)Anaphase 2.

- The cell cycle is highly regulated and involves many steps to ensure that a cell is ready to divide. For this reason, cells cycle between interphase and mitosis. Which of the following describes the consequence of a severe disruption of interphase in cells in healthy tissue? Disruption of interphase will have no effect on mitosis because they are two completely independent processes. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.arrow_forwarda) In which stage of mitosis do chromosomes condense? (b) If a eukaryotic organism has a total of 34 chromosomes, how many pairs will the chromosomes be arranged in? (c) Define homologous chromosomes.arrow_forwardThe DNA located inside of mitochondria exhibits approximately ten times the mutation rate seen in nuclear DNA. Provide an explanation as to why this is the case and what are the effects of this higher mutation rate of mitochondrial DNA on disease processes?arrow_forward
- Which of the following best describes the difference between interphase and mitosis? a) During interphase, DNA has a loose structure that condenses during mitosis. b) During interphase, histones help compact DNA into chromosomes. And once mitosis starts, histones are destroyed. c) During interphase, DNA is tightly packed into chromosomes that uncoil once mitosis starts. d) During interphase, DNA is packed as chromosomes. And during mitosis, DNA is called chromatin. Please I need a surely answer and a quicker responsearrow_forwardWhat is the importance of mitosis for the embryonic development?arrow_forwardwhich stage of the cell cycle do cells spend most of their time in? Explain why you think this is. Explain why mitosis is important to both unicellular and multicellular organisms. discuss how a carcinogen causes mutations that could cause the body to lose control over mitotic events and apoptosis (cell death). What can we do to protect ourselves from the harmful effects of carcinogens?arrow_forward
