Question Description
Q.p53 acts at the G1 checkpoint. If genetic mutations are found, p53 will not allow the cell to proceed to the next step of the cell cycle, which would be ____. (You may consult the attached passage and graphic.)The Cell Cycle:The cell cycle is a carefully regulated sequence of events that involves cell growth and division, resulting in the production of two daughter cells. Cells progress through distinct stages of growth, DNA replication, and division to generate two identical cells. The cell cycle consists of two main phases: interphase and the mitotic phase. Interphase involves cell growth and DNA replication, while the mitotic phase encompasses the separation of replicated DNA and cytoplasmic contents, leading to cell division.In a research study focusing on cell division, scientists cultivate human cells undergoing synchronous division using thymidine. This causes the cells to pause at the G1G1 boundary. Subsequently, the cells are transferred to a thymidine-free medium, which releases the block and allows the cells to resume dividing. Four different samples (A-D) are taken at various time points after thymidine removal to measure the DNA content of the cells. The results for these samples are presented in the graph.Li-Fraumeni Syndrome:Li-Fraumeni syndrome (LFS1) is a rare inherited condition associated with an increased susceptibility to cancer. This syndrome is linked to mutations in the tumor suppressor gene that encodes the transcription factor p53, which plays a crucial role at the G1 checkpoint of the cell cycle. When damaged DNA is detected, p53 halts the progression of the cell cycle. As p53 levels rise, it triggers the production of p21, a protein that enforces the cell cycle arrest. Another form of Li-Fraumeni syndrome, known as LFS2, is believed to be caused by a mutation in the CHK2 gene, which also functions as a tumor suppressor. CHK2 regulates the activity of p53 in the cell cyclea)G0b)G2c)cytokinesisd)S phasee)All of aboveCorrect answer is option 'C'. Can you explain this answer? for MCAT 2025 is part of MCAT preparation.
