Question

which best compares self - renewal and differentiation?
both are processes that are the result of stem cell division.
both create more of the same types of cells.
both form specialized cells.
both depend on gene expression.

Explanation:

• Self - renewal is the ability of stem cells to divide and produce more stem cells (same type). Differentiation is the process by which stem cells divide and become specialized cells. But both self - renewal and differentiation are processes that occur as a result of stem cell division.
• Option 2: Differentiation does not create more of the same type of cells (it creates specialized cells), so this is wrong.
• Option 3: Self - renewal does not form specialized cells (it forms more stem cells), so this is wrong.
• Option 4: While gene expression is involved in differentiation (to turn on/off genes for specialization), self - renewal is more about maintaining the stem - cell state (not primarily about gene expression in the same sense as differentiation for specialization).

Answer:

Both are processes that are the result of stem cell division.
