The $\beta$ subunit of adult hemoglobin has higher sequence similarity to than to __________.
A) fetal $\varepsilon$ subunit; myoglobin
B) myoglobin; fetal $\varepsilon$ subunit
C) adult $\alpha$1 subunit; fetal $\varepsilon$ subunit
D) myoglobin; adult $\alpha$1 subunit

Question

Quizplus · Accepted Answer

The F1F1F1S1F1F1F10 subunit of adult hemoglobin has higher sequence similarity to myoglobin than to the fetal F1F1F1S1F1F1F10 subunit. This is because the F1F1F1S1F1F1F10 subunit is encoded by the HBB gene, which is located on chromosome 11, while the F1F1F1S1F1F1F10 subunit is encoded by the HBE gene, which is located on chromosome 7. The HBB gene is more closely related to the myoglobin gene, which is located on chromosome 22, than it is to the HBE gene.
