A carcinogenic mutation is not inheritable. What could be the reason for this?. A: it occurs in germ cells and can be passed on to decendants during reproduction . B:the mutations could be treated by chemotherapy . C:it occurs in somatic cells and thus are not usually transmitted to descendants

Respuesta :

The possible answer is letter :it occurs in somatic cells and thus are not usually transmitted to descendants

This caused by the radiation or other carcinogens. Even if it occurred in the fetal stages, the embryo will not inherit the carcinogenic mutation,

Answer:

(C). it occurs in somatic cells and thus are not usually transmitted to descendants

Explanation:

Mutations are permanent changes in the genetic material due to alterations in the sequences of DNA molecules. Mutations may be classified as somatic or inherited (or germline).  

Somatic mutations are those mutations that develop in somatic cells and cannot inherit from parents to their offspring.  

Inherited mutations are those mutations that arise in sex cells or gamete-forming cells and transfer from parents to their offspring as these cells form mutated gametes.

A carcinogenic (cancer-causing) mutation is non-inheritable, if it occurs in normal body cells or somatic  cells.

Thus, the correct answer is option (C).
