Mature red blood cells $(RBCs)$

Vedclass · Answer

(A) Mature mammalian red blood cells $(RBCs)$ are specialized cells that lose their nucleus and most organelles,including mitochondria and ribosomes,during maturation to maximize space for hemoglobin. Consequently,they do not contain $DNA$. In contrast,an enucleated ovum (if referring to a laboratory-manipulated one) lacks a nucleus,but a normal ovum contains $DNA$. Mature sperm cells contain a haploid nucleus with $DNA$. Hair roots contain living cells with nuclei and $DNA$.

Which of the following does not contain $DNA$?
