- Which is true for cancer cells: 1) Cell death occurs after a determined number of cell divisions 2) Contact with other cells reduces chance of cell division 3) Cell division occurs in the presence of stop signals.Cytokinesis, the process of cytoplasmic division, occurs shortly after the separated sister chromatids have neared the opposite spindle poles. How is the plane of cytokinesis determined?Not all genes encoded in the DNA are transcribed into RNA or translated into protein. Explain how this mechanism protects the integrity of the cell.
- Cytokinesis in plant cells is different than cytokinesis in animal cells. a) Explain why it has to be different, andb) briefly describe the processes in the two different cell types.After cutting yourself with a knife while chopping vegetables, your body begins extensive mitosis and cell division to begin the healing process. To speed this process, your cells need to make more Cyclin Proteins to bind with extisting cylin- dependent kinase proteins. The DNA below contains the instructions to build cyclin proteins: DNA - TAC GGG CAA ACC TCT AGC CCA ATG TCG ATC Transcribe this into mRNA and translate these into amino acids, use the format below: MRNA: (insert sequence here) Amino Acids: (insert amino acids here)Somatic cells reproduce by______________,while sex cells reproduce by ___________.
- Suppose cells in an experiment had been labeled with green fluorescent tubulin. At the onset of Anaphase B, you use your laser to bleach a stripe across all of the microtubules on one side of the spindle as shown by the dashed line. This does not hurt the function of the microtubules in any way, but the bleached, nonfluorescent subunits in the microtubules now serve to mark a fixed location relative to the (+) and (-) ends. pl. membr. spindle A. Label one of each of the following: kinetochore MT, astral MT, polar MT. Indicate (+) and (-) ends. B. As the cell progresses through anaphase B, do the bleached spots get closer to, further from, or stay the same distance from the spindle pole they are embedded in? Why? Do they get closer to, further from, or stay the same distance from the plasma membrane? Why?Choose all of the TRUE statements. Hint: 4 statements are true. Cytokinesis occurs the same way in both plant and animal cells. Sister chromatids are genetically identical. The term chromosome can be used to describe both chromosomes composed of one and two chromatids. Mitosis results in daughter cells that are genetically identical to the parent cell. All eukaryotic somatic cells are diploid. Cyclin dependent kinases are present but not active in cell cycle regulation without the presence of cyclin proteins. Chromosomes are always visible in the cell.What is the significance of the cell cycle control system and checkpoints? Explain step by step in your own words. [please make it simple]
- Cleavage furrow formed during cytokinesis is found in? A-both in animal and plants B- neither in animal nor in plant cells C- plant cells D- animal cells"Like the lumen of the ER, the interior of the nucleus is topologically equivalent to the outside of the cell" is true or false.Which situation would be the most likely result of a mutation in a eukaryotic organism that causes it to produce less p21 protein than normal? Cells with radiation-induced DNA damage would continue through the cell cycle without repairing the damaged DNA. O Cells with incomplete DNA replication would continue through the checkpoint. Cell replication would be slowed due to an increase in active G1/S cyclin-dependent kinase. Cells would not respond to growth factors. O Cells would have a hypersensitive response to growth factors.
