artcher [175]
An enzyme is sensitive to the environmental conditions. It is affected by various chemical and physical factors. Changes in the environmental factors denatures the enzyme.

4 Variable affecting an enzyme function are as follows:
1. pH: An enzyme is affected by change in pH. Every enzyme has its own specific pH at which it works ideally. 
2. Temperature: An enzyme works best at ideal temperature. Increase or decrease in the temperature causes denaturation of enzyme.
3. ATP: Increase or decrease in the amount of ATP also affects the function of an enzyme.
4. Product: Increase or decrease in the amount of product also affects the ideal functioning of an enzyme.

Hypothesize what potential impact a mutated EGFR allele will have on a cell. Give one possible impact and explain your answer.
NemiM [27]

Answer/Explanation:

EGFR stands for epidermal growth factor receptor. It is a transmembrane protein acting as a tyrosine kinase receptor for epidermal growth factor ligands, which are associated with promoting cell division and proliferation. When epidermal growth factor binds to the receptor, it becomes activated and undergoes dimerization and autophosphorylation.

A mutation could occur making the receptor overactive. That is, it does not require ligand binding to become activated, meaning it is always in an "on" state. This would lead to uncontrolled proliferation, a hallmark of cancer.

A couple has three children, two without sickle cell anemia and one with sickle cell anemia. The mother has sickle cell anemia a
bezimeni [28]

Answer:

Explanation:

The sickle cell allele is recessive. Hence, in order for any child of the couple to have sickle cell anemia, such a child will have to inherit an affected allele each from the two parents. This means that both the father and the mother must have affected alleles in their genotypes. In other words, two sickle cell alleles are required for the abnormality to manifest.

Let us assume that the sickle cell allele is represented by S and the normal allele is represented by A.

Now, it is established that the mother has sickle cell anemia, her genotype would be SS. The father does not have sickle cell, his genotype can either be AA or AS.

Assuming the genotype of the father is AA:

          SS   x   AA

      AS   AS   AS   AS

<em>All the children would be normal in this case.</em>

Assuming that the genotype of the father is AS

           SS    x    AS

      AS   SS   AS   SS

<em>50% of the children would have sickle cell while the remaining 50% would be normal.</em>

<u>Therefore, in order to produce children with sickle cell, the father has to be AS, otherwise, he has to be AA.</u>
