Question

stem cells are undifferentiated cells that have the ability to continue to grow and divide in their nonspecialized state for long periods of time (e.g., months or years). although the genes found within stem cells are the same, stem cells differentiate into unique cell types (e.g., muscle cells, nerve cells, etc.) due to

a. mutations in their genetic code.
b. meiotic division and fertilization.
c. random segregation and proliferation.

Explanation:

Stem - cell differentiation occurs due to gene - expression regulation, not mutations (A is wrong as genes are the same initially), not meiosis and fertilization (which are related to sexual reproduction, not stem - cell differentiation), and not random segregation and proliferation in the context of differentiation. Stem cells differentiate into various cell types because different genes are turned on or off in a regulated manner.

Answer:

None of the above options are correct.
