What is altered hemoglobin? Abnormal hemoglobins result from mutations that change the sequence or number of nucleotides within the globin gene involved, or more rarely, from mispairing and crossover between two like genes during meiosis, creating a fusion protein of both gene sequences. What is hemoglobin chemistry? Hemoglobin, the major component of red blood cells, transports oxygen from the lungs to tissues throughout the body. It also carries some CO2 back to the lungs. Hemoglobin consists of four units, each of which consists of a globin polypeptide chain bound to an iron-containing heme molecule. What is an example of a...
