In chromatin, substitution mutations are most common in linker regions. Option d is the correct answer.
Mutation by substitution When one nucleotide base is replaced by another, this occurs. Mismatch mutation A type of substitution mutation in which a single nucleotide is replaced, resulting in the coding of an incorrect amino acid, which usually results in a malfunctioning protein. Silent mutations are the result of genetic code redundancy (degeneracy): This is false, as silent mutations are the result of a base substitution that has no discernible effect on a protein's amino acid sequence.

The cycle that is described in the problem is called the water cycle. in this cycle, the water from a lake is evaporated through the heat of the sun and the water is accumulated in the clouds. When the clouds are saturated, then water condenses and precipitates to fall as rain.
- - The cell cycle consists of two main phases: interphase and M phase
Nondisjunction could occur during - Anaphase ii
<h3>
What is Nondisjunction ?</h3>
Nondisjunction occurs when the chromosomes do not separate. In this case, gametes are produced with an abnormal number of chromosomes. It is an abnormal number of chromosomes in all cells called aneuploidy or in some cells called mosaicism.
Example ; Down's syndrome, Trisomy of autosomes.
Anaphase is the 3rd stage of cell division process specially after the metaphase in mitosis. In this step sister chromatids gets seperated from each other and pulls towards the cell's ending portion.
specially in Anaphase 2 chromatids splits at the centromere and pulled to the spindle fibres.
