Question

Which of the following Cell does not contain Nucleus:
(A). Myofiber
(B). Neuron
(C). Osteocytes
(D). Red blood Cells
Choose the correct answer from the options given below:

• (A) and (B) only.
• (B) and (C) only.
• (A) and (D) only.
• (D) only.

Hint:

Remember, mammalian RBCs lack a nucleus to maximize oxygen transport, while other cell types retain their nuclei for essential cellular processes.

Answer 1

The Correct Option is D

Red blood cells (RBCs) in mammals are unique among cells as they lack a nucleus. This adaptation provides more space for hemoglobin, which increases oxygen transport efficiency. Other cells like myofibers, neurons, and osteocytes contain a nucleus for regulatory and genetic functions.
