Detailed explanation-1: -So, the correct option is ‘A single base insertion near the start of the coding sequence’.
Detailed explanation-2: -Answer and Explanation: The type of mutation that is likely to have the greatest effect on a protein is B. Nonsense mutation. This is because a nonsense mutation creates a premature stop codon, leading to an incomplete formation of a protein, severely affecting protein structure and function.
Detailed explanation-3: -The answer is A, frameshift mutation. Therefore, multiple amino acids in a protein change.
Detailed explanation-4: -So, the correct option is ‘A missense substitution’
Detailed explanation-5: -A point mutation-the change of a single nitrogen base in a DNA sequence-is usually the least harmful type of DNA mutation.
