Oxygen is carried through the blood by the protein hemoglobin. It is said in the article that a mutation of this protein known as is the result of oxygen poor blood, which appears blue in veins.
A)Hemotosin
B)Methemeglobin
C)Hemolethoglobin
D)Blood Platelets

The correct answer is - B) Methemeglobin.

Explanation:

Methemeglobin is a blood disorder due to the mutation in the hemoglobin which is known as the result of oxygen-less blood. In this disorder, the tissue did not get enough oxygen and appeared to be purple, or blue.

In this mutated form of hemoglobin iron atoms present in ferric instead of the ferrous state and therefore not able to bind with oxygen. It appears blue in veins and tissues look blue or purple.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
