Question

Beginning from the primordial globin gene, how many gene duplications were required to yield the beta subunit of hemoglobin?

3

5

4

2

Answer 1

1. The structure of haemoglobin is tetramer which is formed by two dimers association.
2. The dimers are formed from two alpha and two beta subunits which plays an imporatnt role in carrying oxygen to the cells.
3. Thus the tetramer structure of protein plays an important role.The alpha gene is generally call as alpha complex locus while the non alpha geng are termed as beta complex locus.
4. Therefore for an affective functioning and stable functionallity both are required.
