Step by step
Solved in 2 steps
- What is a stem cell?What are Two kinds of cancer-producing mutations?Which of the following mutations is MOST likely to cause cancer? A) a mutation that causes a cyclin gene to be expressed at all times during the cell cycle B) a mutation that causes an oncogene to be turned off so that no protein is made C) a mutation that causes a Cdk gene to be turned off so that no protein is made D) a mutation that causes a tumor suppressor gene to be over-expressed
- Why is p53 considered a tumor suppressor protein? Question 12 options: a) Because p53 normally detects breaks in DNA. b) Because p53 normally causes progression from G1 to S phase to halt until damaged DNA is fully repaired. c) Because p53 normally repairs breaks in DNA. d) Because p53 normally stimulates transcription of Repair Polymerase. e) Because p53 normally reduces the mutation rate of DNA polymerase.If you were to design an experiment to get p53 back into cancer cells, how would you go about that work? How would you direct p53 into the nucleus of cancer cells without directing it to the nucleus of healthy cells? As an overabundance of p53 in healthy cells would cause problems. Could someone in depth answer these questions for me and explain them cellularly.Which of the following is an example of a proto-oncogene? 1) cell cycle inhibitor 2) tumor suppressor 3) oncogene 4) repair enzyme 5) growth factor receptor
- How genetic mutations convert a benign tumor into a dangerous malignant tumor ?Why would the failure of the p53 tumor supressor gene be more likely to cause cancer in a seventy year old person compared to a ten year old person? Group of answer choices A) The seventy year old is more likely to have pre-existing failures in cell cycle control B) cells divide more rapidly as people get older C) there are fewer mutations in genes controlling the cell cycle in older people D)the p53 gene never works well in old peopleWhat are CDKs? How do they contribute to cell division? Explain.
