Explain the difference between each of the following substitution mutations:

1 answer:

5 0

Answer: silent mutation: a nucleotide base in a codon is replaced with a different base BUT the resulting amino acid isn’t affected.

Missense mutation: similar to a silent mutation, the only difference is that the switch of the nucleotide DOES result in a DIFFERENT amino acid

Nonsense mutation: a nucleotide base is changed, but that change results in a premature stop of translation

(Remember that after transcription, you are left with a strand of mRNA that Is then translated into a protein. The mRNA is read in increments of three nucleotide bases (A,U,G, or C) which is called a codon. That codon makes a single amino acid, and a strand of amino acids makes a protein)

kogti [31]

Answer:

Modified apocrine sweat glands

Explanation:

The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.

As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.

This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.
