Which of the following statements are False?
nata0808 [166]

Answer:

Option D

Explanation:

If an aspartic acid were present in the interior of a globular protein, it would most likely change the conformation of the protein, maybe changing its shape and ultimately its function. To ensure compactness of the interior, hydrophobic amino acid are mainly found in the interior of globular proteins. This acid can be deprotonated and become negatively charged if the surrounding solution's pH is raised changing their isoelectric points.

PKU (Phenylketonuria) is an autosomal recessive disease, in which the synthesis of amino acid Tyrosine from Phenylalanine is blo
prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

p^{2} + 2pq + q^{2} = 1

(0,3)^{2} + 2pq +(0.7)^{2} = 1

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42
