The population in South Africa is more prone to sickle cell anemia (genotype "ss"). People with genotype "ss" survive only up to
lions [1.4K]
The answer is stabilizing selection.

<span>Sickle-cell anemia is a recessive disorder caused by the presence of two recessive alleles "s", so genotype is "ss". This disorder is characterized by sickle hemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle hemoglobin. But pathogen that causes malaria affect only normal hemoglobin, so heterozygous individuals will have half of the hemoglobin resistant to the pathogen and those individuals are resistant to malaria.</span>

Stabilizing selection favors heterozygotes Ss,  disruptive selection favors dominant (SS) and recessive (ss) homozygotes, while directional selection favors dominant (SS) or recessive (ss) homozygote. Since in this example, people with genotype Ss (heterozygotes) are in advantage, then this is an example of stabilizing selection.

A scientist runs an SDS-PAGE experiment two separate times on a protein with a molecular weight of 200 kD. For the first experim
Delicious77 [7]

Answer:

This protein consists of 8 subunits of equal size linked by disulfide bonds

Explanation:

The sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) is a technique widely used in molecular biology laboratories to separate proteins with molecular weights between 5 and 250 kDa. SDS is an anionic detergent used to denature proteins before electrophoresis. SDS can denature proteins by altering non-covalent bonds such as hydrogen, hydrophobic and ionic interactions, but they cannot cleave disulfide bonds. In this case, reducing agents (e.g.,  β-mercaptoethanol or dithiothreitol) have been used to cleave disulfide bonds.
