Explain the Role of telomere in regards to cancer
The assembly and function of the mitotic spindle depend on numerous microtubule-dependent motor proteins. In the mitotic spindle, these motor proteins generally operate at or near the ends of the microtubules. Four major types of motor proteins are:

- 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_forwardThe interphase is the part of the eukaryotic cell cycle that is most transcriptionally active.

This phenotype creates a paradox where mutant cells must also be grown in the lab to further identify the gene and study the role of the protein. How do you think this problem can be solved?arrow_forwardWhich of the following is true with respect to cyclins and CDKs? A) CDKs promote progression of the cell cycle, cyclins function to inhibit progression of the cell cycle B) CDKs are the checkpoints in the cell cycle, and when bound to cyclins, they stop progression of the cell cycle C) CDKs will only work to promote progression of the cell cycle when complexed with their designated cyclins D) CDKs are rarely expressed during a cell's cycle, unless cyclins are present to act as transcription factors .arrow_forward

- A cell inherits a mutation in a gene that results in a transcription factor, called NF-kB, constantly being in its active conformation. When active, NF-kB stimulates the expression of cyclins that promote progression of the cell cycle, regardless of other conditions. As a result of this mutation, how would this cell's phenotype be affected by this mutation? A) This cell would have a cancer phenotype B) This cell would grow larger in size, but would never divide C) This cell would likely undergo apoptosis D) This cell would not duplicate its chromosomes .arrow_forwardThe cell cycle control system is a cycling set of molecules in the cell that triggers and coordinates key events in the cell cycle.
