Fascaplysin is an anti-cancer drug that prevents uncontrolled cell division by preventing the synthesis of cyclins. If cells in 5 phase were given the drug, which stage of the cell cycle would they arrest (get stuck in).

Imagine a cell with a genetic mutation that prevents it from synthesizing functional cohesins. At what stage might the cell cycle be disrupted? If you add a drug that prevents the depolymerization of microtubules, which phase of mitosis would the cells be arrested in? Imagine that an animal cell is treated in G2 with a toxin that prevents polymerization of actin into microfilaments. At what subsequent would the cell cycle probably be disrupted? Cytokinesis, the last stage of the mitotic...

You want to create an anti-cancer drug that destabilizes microtubules, hoping to prevent cell division in the cancer cell line that you are studying. Which of the following drugs would enhance microtubule shrinkage and, therefore, utilize this mechanism of action? Answers A-D A a drug that inhibits GTP hydrolysis by the B-subunit in the GTP cap O B a drug that increases the ability of a tubulin dimer to bind to y-tubulin of the centrosome с a drug that increases...

9. In human cells four different cyclins drive the cell cycle (see picture). Please, note that the cyclins overlap (the picture shows the concentration of each cyclin protein in the cytoplasm). Write a short essay or outline of an experiment to test the following things: How can you figure out how much cyclin protein is present in the cytoplasm at different phases of the cell cycle? B. How can you figure out if there is overlap between the cyclins? For...

If a hypothetical drug prevents actin from working properly, how would cell division be affected? DNA synthesis would not occur cell elongation during anaphase would not occur spindle formation would not occur spindle attachment to kinetochores would not occur cleavage furrow formation and cytokinesis would not occur

Cancer is Uncontrolled Mitosis. Cells that no longer respond properly to cell cycle controls often undergo unrestrained cell division forming abnormal tissues called tumors. If these tumor cells stay within the abnormal tissue, then they are deemed benign and may not harm the individual. However, if the tumor cells invade neighboring tissues and spread to other areas of the body where they can form new tumors, then this type of tumor is called malignant and can adversely affect the affected...

What prevents oocyte to enter M phase? I am working on a meiotic cell division using Xenopus oocyte. I have taken some genomic DNA and after shearing it through a needle, coated a 100 nm beads to act as chromosome to see what would happen if I have extra chromosome in oocyte. when coated beads are injected into germinal vesicle of oocyte, and activate oocyte with progesterone, oocyte does not enter M phase. While, if I had uncoated beads, oocyte...

A cancer cell undergoes cell division in an unregulated manner (for example, when no growth factors are present). Alterations of the following factors could cause cells to exhibit such ‘uncontrolled growth’ characteristics. Determine whether the gene encoding the specified factor behaves like an oncogene/proto-oncogene or a tumor suppressor gene. Briefly explain your reasoning. A kinase that functions in a growth factor signal transduction pathway. A CDK that functions in cell cycle regulation. A kinase that functions to turn off the CDK described in...

A drug derived from the neem tree (Gedunin) was found, it inhibited cell division and induced apoptosis in a human carcinoma cell line. Why would it be “good” for Gedunin to induce apoptosis in the cancer cells?
