Viktor [21]

Answer:

Mutations are only passed on to offspring when they occur in germ cell DNA, which are the cells that create sperm or ova. The other kind of cells, somatic cells, are the rest of the cells in the body, and mutations that occur in these cells do not get passed on to offspring.

When a protein is treated with a reducing agent such as 2-mercaptoethanol it becomes denatured. The interactions stabilizing the
Andreas93 [3]

Answer:

Disulfide linkage/bond

Explanation:

The tertiary and quarternary structure of the protein is stabilized by Disulfide linkage which is formed between two thiol groups in the protein. 2-mercaptoethanol is a reducing agent that breaks this disulfide bond.  

A protein becomes denature when it loses its native configuration and becomes inactive. So as 2-mercaptoethanol breaks disulfide bond in protein it looses its native configuration and becomes denatured. 2-mercaptoethanol  is used in SDS-PAGE to separate protein subunits. Therefore the correct answer is Disulfide linkage/bond.

serious [3.7K]

Out of the following given choices;

<span>A.      </span>The mouse has a completely different DNA sequence than the other mice.

<span>B.      </span> The substituted nucleotide has the same directions as the original nucleotide.

<span>C.      </span>Substitutions in the nucleotides of a mouse's DNA never affect their phenotypes.

<span>D.      </span>DNA sequences don't determine the color of a mouse's fur.

The answer is B. Most probably, the nucleotide substitution did not translate to a change in the amino acid sequence in the translated protein. As you may be aware, most amino acids are coded by more than one codon. For example, Leucine is coded for by CTT, CTC, CTA, CTG, TTA, TTG. Therefore, a substitution, that causes a change to either one of the sequences will not change the amino acid.
