The Ras protein found in tumors usually cause which of the following events to occur excessive cell division.
<h3>How does Ras oncogene contribute to cancer?</h3>
Ras genes codes for proteins that can drive cancer when mutated.
All Ras proteins are GTPases which work as molecular regulators in the cell, controlling signaling pathways and other interactions.
Thus, option "A" is correct.

So in order to form a new organism, two gametes -- the sex cells, sperm and egg -- must fuse, further mixing the genes to produce more genetic diversity. Asexual reproduction is one organism dividing into two organisms without shuffling its genes, so the offspring has the same version of genes as did the parent.
The answer is C.
The man’s genotype must be AB. The woman’s genotype can be either BB or BO as both correspond to a blood type (which is a phenotype) of B.
Each parent passes on one allele. The man can contribute A or B and the woman can contribute B or O.
The possible genotype combinations are therefore AB, AO, BB, and BO. These correspond to the phenotypes AB, A, B, and B.
