What is the mutational basis of an "elongation hemoglobin?"

Question

Quizplus · Accepted Answer

An elongation hemoglobin is a type of hemoglobin with a longer amino acid chain than normal hemoglobin. This is caused by a mutation in either the alpha or beta globin chain gene, where a single base pair mutation or frameshift occurs at the 3' end of exon 3 or the 5' end of exon 1. This leads to the addition of extra amino acids, resulting in the elongation of the hemoglobin chain. Therefore, choice D is the correct answer.
