Mutations in the nucleic acid sequence of a gene can sometimes direct the substitution of one amino acid for another in the enco
N76 [4]

Answer: Leucine to lysine

Explanation:

Leucine is an hydrophobic amino acid and lysine is a basic amino acid. Most of the time, disruption of the normal structure of a protein can occur if the two amino acids substituted have different properties eg chemical properties. Hydrophobic substances normally cluster up within buried sites preventing contact with the fluidic environment while some charged ones are found at the surfaces. Thus substition of leaving which is a hydrophobic amino acid for lysine, a basic amino acid will cause distruption of the normally cluster up buried regions.

The left coronary artery typically branches into the __________ interventricular artery and the __________ artery.
ANTONII [103]

The left coronary artery typically branches into the anterior interventricular artery and the circumflex artery.

<h3>What is the circumflex artery?</h3>

The circumflex artery is an artery that branches from the left coronary artery, which is one of the most important arteries in the body.

The circumflex artery is well known to envelop and surround all the heart muscle (cardiac muscle).

The circumflex artery is a fundamental blood vessel in the heart and its damage may have serious health problems.

If the frequency of one allele in a population is 0. 7 in a population with two alleles at a particular locus, what is the frequ
Kipish [7]

According to Hardy- Weinberg principle, if the frequency of one allele in a population with two alleles is 0.7 at a particular locus, then the frequency of alternate allele is 0.3.

<h3>What is Hardy- Weinberg equilibrium?</h3>
  • Hardy- Weinberg rule states that in the absence of disturbing factors, the genetic variability in a population remains constant in different generations.
  • It states that when mating is random both the genotypic and allelic frequencies remain constant as they are in equilibrium.
  • Hardy- Weinberg rule applies to a large population where mating is random and there is no migration.
  • It is given by p + q = 1, where p is the frequency of dominant allele in the population, q is the frequency of recessive allele in the population.
  • By squaring, p2+ 2pq+ q2= 1, where p2 is percentage of homozygous dominant individuals, q2 is percentage of homozygous recessive individuals. 2pq is percentage of heterozygous individuals.
  • Here given, p= 0.7, therefore q= 1- 0.7= 0.3
