8 0

Answer:

DNA

Explanation:

Mutations are changes to an organisms DNA that creates diversity within a population by introducing new alleles. Some mutations are harmful and are quickly eliminated from the population by natural selection harmful mutations prevent organisms from reaching sexual maturity and reproducing.

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp m
kodGreya [7K]

Answer:

A mutation in Ras protein which will cause hyperactivity will eventually lead to cancer.

Explanation:

Ras protein was first discovered in Rous sarcoma virus (RSV) and it is a proto-oncogene product. In normal conditions, it plays an important role in cellular signalling but in case of gain of function/hyperactivity it gets converted into cellular oncogene. In several types of cancers a point mutation has been reported in Ras protein.

Just like G protein, it is also a GTPase switch protein but unlike G protein which is trimeric, it is monomeric. In the plasma membrane, it is attached with the help of lipids like prenyl or palmitoyl groups. During signal transduction pathway when it gets activated, it downstream activates MAPK pathway and causes gene expression but when it gets hyperactivated it causes over expression of genes leading to cancer.
