Question 7: The TERT gene encodes for telomerase and is an example of a(n) Oncogene. (TERT (Telomerase reverse transcriptase) is considered as a proto-oncogene which when undergo mutation at promoter region codes for excessive telomerase responsible for lengthening of telomeres and causes cancer.)

Question 9: Their environments are ideal for rapid cell growth, providing nutrients and oxygen. (The tumor is a heterogeneous mass of cells containing actively proliferating cells. It is well nourished with oxygen and nutrients with the help of own blood supply.)

Question 10: during surgery to remove a primary tumor, nearby lymph nodes are often additionally removed or biopsied to look for the presence of invasive cancer cells. (Lymph nodes are only places where some of the tumor cells can be found. That’s why some time before biopsy nearby lymph nodes are removed and checked for cancer cells. During removal of primary tumor nearby lymph nodes are removed to get rid of tumor cells completely.)

Gene X encodes a repressor that represses gene Y, which also encodes a repressor. Both X and Y negatively regulate their own promoters. (a) At time t=0, X begins to be produced at rate β, starting from an initial concentration of X=0. What are the dynamics of X and Y? What are the response times of X and Y? Assume logic input functions, with repression thresholds Kxx, Kxy for the action of X on its own promoter and on the...

A gene is 8,001 nucleotides in length. Studies of this gene show that it encodes a protein only 400 amino acids long – far shorter than the 2,667 amino acids that were expected. This is best explained by the fact: nucleotides often break off and are lost during the transcription process. the genetic code is ambiguous (unclear). in some cases, many nucleotides are used to encode a single amino acid. many of the 8,001 nucleotides of the gene are ultimately...

A strain of bacteria possesses a temperature sensitive mutation in the gene that encodes the rho subunit. At high temperatures, rho is not functional. When these bacteria are switched to elevated temperature, which of the following effects would you expect to see? Explain your reasoning for accepting or rejecting these options. 1. Transcription does not take place at high temperature. 2. All RNA molecules produced are shorter then normal at high temperature. 3. Translation does not take place at high...

In a diploid organism, the IND gene encodes a transcriptional activator that binds to an enhancer upstream of the EXP gene. The REP2 gene encodes a repressor protein that binds to IND and blocks its activation domain in the absence of an inducer called costar. In the presence of costar, REP2 protein no longer blocks the activation domain of IND. Both genes (IND and RE2) are expressed in all cells. There are complete loss of function mutants available for both...

6. The p53 tumor suppressor gene was isolated from a tumor where p53 protein levels were very high. This was likely due to dominant-acting mutant that inactivated all p53 tetramers and blocked the tumor suppressing effects of wild type p53. A) True B) False 7.

The gene REG encodes an activator protein (REG). REG is a transcriptional activator involved in the regulation of the gene YLW. You are studying a species of flowers where the YLW protein is involved in flower petal colour. You have generated a number of mutant flower lines, and are measuring the amount of REG transcription that occurs in each line. The results are below: Note: The results are given relative to wild-type/unmutated (e.g., a transcription level of 100% in a...
