Question

Suppose a genotype for a protein-producing gene can have any combination of three alleles, A₁, A₂, and A₃.

Each allele produces a protein with a distinct electrophoretic mobility. Allele A₁ has the highest electrophoretic mobility, A₃ has the lowest electrophoretic mobility, and the electrophoretic mobility of A₂ is intermediate between them. Draw the appearance of gel electrophoresis protein bands for each of the possible genotypes. Be sure to label each lane of the gel with the corresponding genotype.

Accepted Answer

Hello everyone and welcome to today's video to the H B B gene codes for a protein known as Bear A Globe in an imitation in both the leos of the H B B gene causes sickle cell disease. The A Leo for wild type better global protein is designated by B A and that formula and global protein is designated by vera S. How many protein bands do you expect to see if you run a sample from a person with sickle cell disease through gel electro phrases? Remember that this gel electro phrases is going to separate the proteins that are created based on charge. So if there are proteins that are of a different nature, these are going to be separated and they're going to exist as different bands in the sample. Now remember that this mutant genotype which is going to create this sickle cell disease is going to be beta S and beta is this is going to be recessive in that way. Meaning that the only a leo that is going to be present is this mute and vera S A Leo, meaning that the only protein that is going to be created is the mutant protein which causes sickle cell disease because we have only wanna leo that means that only one type of protein is going to be created, which means that one band will show up in jail electro phrases as a result of the existence of a single mutant protein. So here the correct answer choice here is going to be answer choice. Only one band of gel electrophoresis is going to show up for a person with sickle cell disease. I really hope this video helped you and I hope to see you on the next one.
