Question

What causes the stem cell to differentiate into one or more types of specialized cells?

A) Mutation of stem cell genes at the time of cell division
B) Expression of different genes by both cell types
C) Inheritance of different types of DNA by both the cells
D) Difference in the rate of motorized division in the 2 cells

Answer 1

Answer: The correct answer is B) Expression of different genes by both cell types

Step-by-step explanation: Stem cell-specific protein OCT4 primes certain genes that, when activated, cause the cell to differentiate, or become more specialized.

Answer 2

When unspecialized stem cells give rise to specialized cells, the process is called differentiation. ... The interaction of signals during differentiation causes the cell's DNA to acquire epigenetic marks that restrict DNA expression in the cell and can be passed on through cell division
