Which of the following are characteristics of both cancer and development?

Group of answer choices

a. Development, like cancer, is an active process that never ends throughout the life of the cell.b.

b. Both cancer and development can accelerate mutagenesis.

c. Both cancer and development involve rapid global changes in gene expression.

Question 32:

Gain of function mutations tend to be _______________

Group of answer choices

a. Conditional

b. Incompletely dominant

c. Recessive

d. Dominant

e. Epistatic

Answer 1

31) Cancer occurs due to uncontrolled growth of the cells. Development occurs when the cell decides to follow a particular cell fate and perform that function. So development cannot occur all throughout life. Cancer is an active process but it will not accelerate mutagenesis, rather it will be caused by a mutagenic change and will keep dividing with that mutation. So the correct answer is : c - Both cancer and development involve rapid global changes in gene expression. Because cancer is done by upregulation or downregulation of gene expression and so is development because that is what decides the cell fate.

32) Gain of function mutation occurs when the change in the gene due to mutation brings out new functions in the gene. This kind of mutation normally takes over the function of the reciprocal gene. So the correct answer is : d- dominant
