Question

multiple choice question
mature red blood cells are unable to divide or undergo protein synthesis. what feature of the cell accounts for this?
o abundance of hemoglobin; limited cytoplasm
o lack of nucleus and other organelles
o biconcave shape of the cell

Explanation:

Protein synthesis and cell - division require genetic material (DNA) in the nucleus and organelles like ribosomes. Mature red blood cells lack a nucleus and most organelles, which prevents them from dividing or synthesizing proteins. The abundance of hemoglobin and limited cytoplasm, as well as the biconcave shape, are related to their oxygen - carrying function, not their inability to divide or synthesize proteins.

Answer:

B. Lack of nucleus and other organelles
