DNA is the material that makes up genes.
The term DNA means Deoxyribonucleic acid. It has been found to be the hereditary material that is found in genes.
DNA is comprised of a double helix of complimentary amino acids arranged in specific sequences.
These specific arrangements of amino acids encode genetic information found in genes. This genetic information is replicated during cell division.

Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Strands of hair originate in an epidermal penetration of the dermis called the hair follicle. The hair shaft is the part of the hair not anchored to the follicle, and much of this is exposed at the skin’s surface. The rest of the hair, which is anchored in the follicle, lies below the surface of the skin and is referred to as the hair root. The hair root ends deep in the dermis at the hair bulb, and includes a layer of mitotically active basal cells called the hair matrix. The hair bulb surrounds the hair papilla, which is made of connective tissue and contains blood capillaries and nerve endings from the dermis.
The right answer is: neutral mutation.
Neutral mutation is a nucleotide change in the DNA of the leading to the replacement of one amino acid by another amino acid possessing the same physicochemical properties.
example: AAA to AGA (Lysine to Arginine).
both these two amino acids are positively charged, so the charge of the protein will not change
The answer is <span>The q allele will go up.
Let's assume that the population is in the Hardy-Weinberg equilibrium and there are only two alleles of some gene. </span>The Hardy-Weinberg principle can be expressed as p + q = 1 where p is the frequency of the p allele and q the frequency of q allele.
Let initial frequencies be:
p = 0.6
q = 0.4
p + q = 1
0.6 + 0.4 = 1
Now, after the environmental change, the frequency of the p allele has gone down, for example p = 0.3
So, p goes from 0.6 to 0.3.
The frequency of the q allele can be calculate using Hardy-Weinberg principle:
p + q = 1
q = 1 - p
q = 1 - 0.3
q = 0.7
Thus, q goes from 0.4 to 0.7.
