- Why interphase is called prepering phase?arrow_forwardDuring cell division what does the centrosome generates?arrow_forwardThe interphase is the part of the eukaryotic cell cycle that is most transcriptionally active. Gene regulation during this phase involves changes in the chromatin. a) What is chromatin? b) How can the chromatin structure change?arrow_forward
- The p53 pathway is important for regulating the cell cycle. In a normal cell, there is a protein called mdm2 that can bind to p53 and deactivate it. A diseased individual has amutation in the gene that codes for mdm2, resulting in an mdm2 protein that is less able to bind to p53. Will this mutation increase, decrease, or cause no change in the rate of cell death? Explain.arrow_forwardA small amount if cytoplasm isolated from a mitotic cell is injected into an unfertilized frog oocyte, causing the oocyte to enter M phase. A sample of the injected cytoplasm is then taken and injected into a second oocyte, causing this cell also to enter the M phase. this process is repeated many times until essentially, none of the original protein samples remains, and yet, cytoplasm taken from the last in the series on injected oocytes is still able to trigger entry into the M phase with undiminished efficiency. Explain this remarkable observation.arrow_forwardDescribe the organization of the interphase nucleus.
