The gene frequency for a dominant allele is 0.68 and the recessive allele is 0.39. What percent of the population has a homozygo
Alinara [238K]

Answer:

15.21 %

Explanation:

If we recall the basic formula of Hardy-Weinberg's equilibrium ; we have the following below:

p + q = 1

p² + 2pq + q² = 1

where;

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p² = percentage of homozygous dominant individuals

q² = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

Given that p= 0.68 and q = 0.39

the percentage of the homozygous recessive genotype (q² ) will be

(0.39)² = 0.1521

= 0.1521 × 100

= 15.21 %

∴ the percentage of the population that has a homozygous recessive genotype = 15.21 %

What enzyme catalyzes the attachment of an amino acid to trna?
3241004551 [841]
The answer is an aminoacyl-tRNA synthetase.

<span> The aminoacyl-tRNA synthetase is an enzyme responsible for the attachment of an amino acid to tRNA. First, it binds the ATP and the amino acid which results in aminoacyl-AMP and inorganic pyrophosphate. Aminoacyl-AMP binds the appropriate tRNA molecule. The aminoacyl group dissociates from the complex with AMP and binds the tRNA molecule creating aminoacyl-tRNA.</span>
