Answer:
The correct answer is : oxygen
Explanation:
- Oxygen is carried in the blood by two means:
- About 2% of the oxygen is carried in the dissolved form in blood plasma and in the water present in the red blood cells (RBCs).
- Rest 98% of the oxygen is carried in bound form with the haemoglobin as oxy-haemoglobin inside the RBCs.
- RBCs lack nucleus. This place is occupied by hemoglobin molecules that binds to oxygen and form oxy-hemoglobin.
- This increases the capacity of each RBC so that it can carry more oxygen to all the parts in the body.
<u>Substituion mutation</u> is responsible for small changes in a trait.
Explanation:
This kind of mutation merely changes the type of nucleotide in the DNA sequence. The mutation does not cause a frameshift as would a deletion of addition mutation.
A substitution mutation would at worst change an amino acid in the translated protein. This would likely have a slight effect on how the protein folds into an active protein. On the other hand, mutations that cause frameshifts have the biggest effect on the proteins. They change all the amino acids of a protein downstream of the point of mutation.

Answer:
A) Humans without this gene exhibit problem with oxygen binding in their red blood cells.
Explanation:
- Oxygen binds to red blood cells because of their hemoglobin component. It is a protein found in red blood cells.
- Each hemoglobin molecule is able to bind to four oxygen molecules.
- If the gene controlling hemoglobin production is absent in humans, the red blood cells will not be able to bind to oxygen.
- Hence, if the gene given in diagram is removed and it results in difficulty in binding of oxygen to red blood cells, that gene might be involved in hemoglobin production.
