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.

Because only the chromosomes can be seen in a karyotype, and microdeletions or insertions are mutations at the molecular level, it is virtually impossible to detect such mutations at the chromosomal level.
With the sequence of the gene-coding regions of the human genome in hand and the development of newer sequencing methods, scientists are able to
1. develop new forensic tests that can help in the identification of the convict.
2. diagnose genetic diseases before their onset.
3. develop customised medicines based on the genetic profile of the patient.
4. therapeutically target the cancer causing genes (oncogenes) in the patients.
5. understand the inheritance of genes especially the rare mutations in a population.
