In sickle-cell disease, malformation of red blood cells is caused by only one mistake for one amino acid in the genetic code for

hemoglobin.

Answer:

A. True

Explanation:

Hemoglobin is a protein and has two distinct types of polypeptide chains. These are called the alpha and beta subunits. The gene that code for the beta chain undergoes a mutation in a single base that causes sickle cell anemia. Here, adenine base in the genetic code for glutamic acid is substituted with a thymine base.

The genetic code for glutamic acid in the beta chain gene is GAG. The "A" is replaced with "T" and the new code "GTG" codes for valine. Therefore, the mutated hemoglobin has valine in place of glutamic acid. This makes these mutated protein molecules to form aggregates resulting in a change in the shape of RBCs carrying them.

The value of n, the Hill coefficient, for hemoglobin is about _________ as great as the value for myoglobin.
ludmilkaskok [199]

The value of n, the Hill coefficient, for hemoglobin is about 2 to 3 times as great as the value for myoglobin.

Hill Equation

The two closely related equations that help to explain the binding of macromolecules to ligands are called the Hill equation. It helps to quantify the interaction between various ligand binding sites.

Hill coefficient

It is used to describe the cooperativity of ligand binding. It can be positive and negative depending on the value of the Hill coefficient. If the value of the Hill coefficient is more than one then it exhibits positively cooperative binding and if it is less than one then it exhibits negatively cooperative binding. Then there is the noncooperative binding where the Hill coefficient value is one. As for the hemoglobin and myoglobin, the values are,

  • Hill coefficient of hemoglobin is 2.7 - 3.
  • Hill coefficient of myoglobin is 1.0.

Thus hemoglobin is positively cooperative and myoglobin exhibits noncooperative binding.
