The cancer-causing forms of the ras protein are involved in which of the following processes?
A
Cell cycle regulation
B
DNA replication
C
Apoptosis
D
Protein synthesis
Verified step by step guidance1
Understand that the ras protein is a type of GTPase that plays a crucial role in cell signaling pathways.
Recognize that mutations in the ras gene can lead to uncontrolled cell division, which is a hallmark of cancer.
Identify that the primary process affected by cancer-causing forms of the ras protein is cell cycle regulation, as these mutations can lead to continuous cell proliferation.
Differentiate between the processes listed: DNA replication, apoptosis, and protein synthesis, and understand that while they are important cellular processes, the direct involvement of mutated ras proteins is primarily in cell cycle regulation.
Conclude that the correct answer is cell cycle regulation, as the mutated ras protein disrupts normal cell cycle control, leading to cancer development.
