Do red blood cells have DNA?

YES. Red blood cells of birds have nucleus and thus DNA. In humans, when developing in bone marrow have a nucleus and then genomic DNA . Rbc's are derived from haematopoietic stem cells in bone marrow. read more

Mature red blood cells do not have nuclei hence no DNA. They loose their nucleus as they mature, making them efficient oxygen carriers. However, immature red blood cells called reticulocytes do contain nucleus and hence DNA ,reducing their oxygen carrying capacity compared to mature RBC. read more

The proteins of the membrane skeleton are responsible for the deformability, flexibility and durability of the red blood cell, enabling it to squeeze through capillaries less than half the diameter of the red blood cell (7–8 μm) and recovering the discoid shape as soon as these cells stop receiving compressive forces, in a similar fashion to an object made of rubber. read more

Red blood cells do not have a nucleus, so they do not have DNA. Hemoglobin can be made by other cells (like cells in the bone marrow) that have DNA that codes (or instructs) for the protein hemoglobin. read more
