Hemopoiesis means –

Correct option is A

Sol. Hemopoiesis refers to the formation of all types of blood cells including RBCs, WBCs, and platelets.
Explanation of each option:
· (a) Synthesis of RBC – Correct. Hemopoiesis involves the production of all types of blood cells, including red blood cells (RBCs). It is a key part of the process by which blood cells are generated in the bone marrow.
· (b) Destruction of RBC – Incorrect. The destruction of RBCs is called hemolysis, not hemopoiesis. Hemopoiesis refers specifically to the formation, not destruction, of blood cells.
· (c) Synthesis of proteins – Incorrect. The synthesis of proteins occurs in the ribosomes and is part of cellular processes like protein translation, but it is not directly related to hemopoiesis, which deals with blood cell formation.
· (d) Synthesis of DNA – Incorrect. The synthesis of DNA involves DNA replication, which is a part of cell division and not directly involved in blood cell production. While DNA replication is required for the division of cells, it is not the main function of hemopoiesis.
