Answer 1

ANS.1. Option C is the correct answer.

Explanation;- A mutation in which one nitrogenous base is substituted for another can be missense , nonsense or silent. Missense mutation arise from the substitution of the nitrogenous base by another nitrogenous base.It can change the mRNA base sequence. In the nonsense mutation, in which a codon is changed to a premature stop codon. Another mutation are mutations in DNA that do not have an observable effect on the organism's phenotype.

ANS.2. Option A is the correct answer.

Explanation;- It is a missense mutation. The example of the missense mutation is point mutation in the beta globin subunit of the hemoglobim. It can cause the haemophillia.

ANS.3. Option E is the correct answer.

Explanation;- Felis catus is in italics language. In scientific nomenclature, the first name indicate the generic name and the second name indicate the species name. The are always written in italics.
