NEETZoologyMolecular Basis of Inheritance
Component Description A. Silent Mutation 1. Change in nucleotide that does not alter the amino acid sequence. B. Missense Mutation 2. Change in nucleotide that results in a different amino acid. C. Nonsense Mutation 3. Change in nucleotide that creates a premature stop codon. D. Frameshift Mutation 4. Addition or deletion of nucleotides that alters the reading frame.
Options
- AA - 1, B - 4, C - 3, D - 2
- BA - 2, B - 1, C - 4, D - 3
- CA - 3, B - 1, C - 2, D - 4
- DA - 4, B - 3, C - 2, D - 1
Correct answer
A. A - 1, B - 4, C - 3, D - 2
Step-by-step solution
A - 1: Silent mutations do not alter the amino acid sequence despite changing the nucleotide. B - 4: Frameshift mutations involve the addition or deletion of nucleotides, changing the reading frame of the codons. C - 3: Nonsense mutations create a premature stop codon, truncating the protein. D - 2: Missense mutations change one amino acid in the protein sequence.
