Of the four genes found in the Rous sarcoma virus,which provides tumor suppression ability?
A) Gag
B) Env
C) Pol
D) V-src
E) Gag and Env

Accepted Answer

The gene V-src found in the Rous sarcoma virus provides tumor suppression ability. This gene encodes for a tyrosine kinase protein that activates signaling pathways, leading to uncontrolled cell growth and tumor formation. However, a mutated form of this gene, called c-Src, is found in many human cancers and promotes tumor growth.
