Homework Answers
Ras gene controls cell growth. The mutant Ras gene is an oncogene, however, the wild type acts as a tumor suporessor gene.
There are 3 different mutations of Ras which can cause cancer; H-ras, N-ras, K-ras.
If ras gene is mutated then, the cell will exhibit increased growth & division

1.The KRAS gene encodes the KRAS protein which functions to promote cell growth and division. A single base-pair deletion occurs in exon 4 of the KRAS gene that results in an early stop codon. This mutation results in an unregulated KRAS protein that always sends growth signals. What is a correct classification of the normal (wildtype) KRAS gene? A) A tumor suppressor gene B) An oncogene C) A tumor activating gene D) A DNA repair gene E) A proto-oncogene 2....

The dopamine transporter gene encodes a protein required to re-uptake dopamine into the pre-synaptic neuron from the synapse. How might a variant allele of the dopamine transporter gene, which results in a transporter protein with increased function , be involved in predisposing an individual to addictive behavior? A) The dopamine transporter variant allele would produce more dopamine in response to addictive behavior B) The dopamine transporter variant allele would produce less dopamine in response to addictive behavior C) The dopamine...

1.) You are studying a particular type of cancer. You observe that the cells are expressing higher than normal levels of the activated version of the G protein Ras (ie, they contain more Ras-GTP than normal). a.(2 pts) Further study shows that the one of the Ras genes has been mutated, would you classify this as the mutation of a tumor-suppressor gene or an oncogene? b.(2 pts) Given your knowledge of the regulation of G proteins, suggest an explanation for...

A cancer cell undergoes cell division in an unregulated manner (for example, when no growth factors are present). Alterations of the following factors could cause cells to exhibit such ‘uncontrolled growth’ characteristics. Determine whether the gene encoding the specified factor behaves like an oncogene/proto-oncogene or a tumor suppressor gene. Briefly explain your reasoning. A kinase that functions in a growth factor signal transduction pathway. A CDK that functions in cell cycle regulation. A kinase that functions to turn off the CDK described in...
