Glutamic acid is a hydrophilic amino acid. At physiological pH, it is negatively charged. Carboxylic acid group ( -COOH ) in its side chain is responsible for both, the hydrophilic nature as well as negative charge of the glutamic acid. Because of its hydrophilic nature it is found on the surface of protein facing aqueous solution i.e. it is an extrinsic amino acid.
Valine on the other hand is a hydrophobic amino acid. It is neutral at physiological pH. Valine has an aliphatic side chain which is responsible for both, it's hydrophobic nature as well as neutral charge. Since it is hydrophobic, it is found inside of protein molecules i.e. it is an intrinsic amino acid.
Answer:
Explanation:
A sperm and an egg each contain one set of 23 chromosomes. When the sperm fertilizes the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms.
Answer:
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition
Explanation:
The risk of recurrence of a trait based on known incidence in a population refers to the empiric risk.
<h3>What is empiric risk?</h3>
Disorder present in a family member will reoccur in other family member after some period of time.
Cancers are very difficult to treat so it has high rate of recurrence such as leukemia it has 9% to 29% recurrence rate depending upon risk.
The recurrence chance for Down syndrome is nearly 1%.
The chance of recurrence risk in future offspring is 3% - 5% if a parent or sibling is affected with a disorder.
Therefore,the risk of recurrence of a trait based on known incidence in a population refers to empiric risk.
