Final answer:
Ras mutations that keep Ras protein constantly active are a common feature of many human cancers.
Step-by-step explanation:
True. Ras mutations that keep the Ras protein constantly active are indeed a common feature of many human cancers. The Ras protein is a G-protein that plays a crucial role in signal transduction pathways.
When Ras is continuously activated due to mutations, it can lead to uncontrolled cell division and contribute to the development of cancer.
