Compare and contrast the two new cells formed in mitosis and cell division
Makovka662 [10]
The parent cell is also making a copy of its DNA to share equally between the two daughter cells. The mitosis division process has several steps or phases of the cell cycle—interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis—to successfully make the new diploid cells

One method for separating polypeptides makes use of their different solubilities. The solubility of large polypeptides in water
Naddika [18.5K]

Answer:

The solubility of any substance in water depends on its polarity. The polar molecule dissolves more easily in the water than the non polar molecule. Amino acids have different polarity at different pH.

(a) (Lys-Ala)3 : The (Lys-Ala)3 contain more positive charge and highly polar the at pH 7 as compared with the  (Gly)20 that remains uncharged and has less polarity.

(b) (Glu)20 :This amino acids negatively charged at pH 7 and highly polar than the (Phe-Met)3 which is non polar or less polar and hence least soluble  in water.

(c) (Asn-Ser-His)5 is highly polar at pH 3 as compared with the (Ala-Asp-Gly)5 that contains the carboxylate groups of Asp residues that are partially neutral. The  (Asn-Ser-His)5 contains = the imidazole groups of His residues are fully polar and soluble in water.

(d) (Asn-Ser-His)5 is polar at pH 6.0 because both have polar side chains Ser but (Asn-Ser-His)5 is only partially partially protonated due to the His side chains. Thus,  (Asn-Ser-His)5 is more soluble in water.

Select all that apply. Factors that can increase mutation rates are _____. high temperatureslow temperaturesfood additivesUV ray
Artemon [7]
<span>Factors that can increase mutation rates are high and low temperatures, food additives, and UV rays. All of these answers are correct. Mutation rates in genes vary depending on many environmental effects. UV rays, along with varying temperatures, can cause mutations during cell division due to the damage they impart on the cells that are dividing. Dangerous food additives are believed to cause mutations, as seen in animal studies (ie. aspartame causing cancer in rats).</span>
