Mutated DNA #1 is an example of missense mutations, where a single amino acid in the protein is changed.
Mutated DNA #2 is an examples of nonsense mutations
Mutated DNA #3 is missense mutation, where a single amino acid in the protein is changed.
Mutated DNA #4 is a nonsense mutation, causing the premature termination of protein synthesis.
Mutated DNA #1 is Missense mutation because A single nucleotide change (C to G) has resulted in a change in the amino acid sequence (His to Gln).
Mutated DNA #2 is a Missense mutation because A single nucleotide change (T to C) has resulted in a stop codon, which prematurely terminates translation.
Mutated DNA #3 is a Frame shift mutation because A single nucleotide change (G to C) has resulted in a change in the amino acid sequence
