what would be the
likely effect of a mutation that prevented the formation of memory cells?
Step by step
Solved in 2 steps
- Based on the information provided in Figure 22.21, what would be the likely effect of a mutation that prevented the formation of memory cells?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.What is a tumor suppressor? What is an oncogene?
- D) The level of carbon dioxide increases with the level of available oxygen. 60) The TP53 gene provides instructions for making a protein called tumor protein p53. Known as the guardian of the genome, this protein acts as a tumor suppressor, which means that it regulates cell division by keeping cells from growing and dividing too fast or in an uncontrolled way. The p53 protein is located in the nucleus of cells throughout the body, where it attaches directly to DNA and plays a critical role in determining whether the DNA will be repaired or the damaged cell will self- destruct (undergo apoptosis). If the DNA can be repaired, p53 activates other genes to fix the damage. If the DNA cannot be repaired, this protein prevents the cell from dividing and signals it to undergo apoptosis. eg Suppose chromosomes in a skin cell are damaged by ultraviolet radiation. If the damaged genes do not affect p53, which choice correctly predict if the cell will become cancerous and why? No, the cell will…What are Tumor Markers ?What would happen if the retinoblastoma protein wasn't able to bind to the E2F transcription factor?
