Question

challenge question: three closely related members of the ras gene family (rash, rask, and rasn) are the oncogenes most frequently encountered in human tumors. these genes are involved in approximately 20% of all human malignancies, including about 50% of colon and 25% of lung carcinomas. if an individual acquires a mutation in their rask gene, a potential outcome might be...

...that the cell will die.

...that the cell will be unable to recognize abnormal growth and thus will not be able to stop it.

...that the cell induce multiple mutation in neighboring cells, leading to a tumor.

...that the cell will undergo more rapid growth because it cannot regulate normal growth appropriately.

Explanation:

Ras genes are oncogenes. Mutations in oncogenes often lead to uncontrolled cell - growth as they disrupt normal growth - regulating mechanisms. A mutation in rasK gene would likely cause the cell to grow more rapidly due to its inability to properly regulate normal growth. The cell is not likely to die as oncogene mutations promote cell survival and proliferation. It's not about recognizing abnormal growth (that's more related to tumor - suppressor genes), and it doesn't directly induce mutations in neighboring cells.

Answer:

...that the cell will undergo more rapid growth because it cannot regulate normal growth appropriately.
