Pauling used gel electrophoresis to confirm that homozygous individuals produce a single form of β-globin protein that differs depending on the homozygous genotype as well as that heterozygotes produce proteins of both types in approximately equal concentration.What characteristic(s)of the bands proved this?

Question

Quizplus · Accepted Answer

The positions of the protein bands show the size and charge of the β-globin protein, which can differentiate between the different homozygous genotypes. The densitometry peaks of each band show the concentration of the protein, indicating that heterozygous individuals produce both types in approximately equal concentration. Therefore, both the positions and the densitometry peaks of each band provide evidence to confirm the production of single or multiple forms of β-globin protein by different genotypes.
