Detailed explanation-1: -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-2: -Chromosome mutations are potentially more dangerous than gene mutations because they can be swapped and transferred to that parent’s child. When a chromosome mutates, whole sets of genes are altered versus 1 gene.
Detailed explanation-3: -There are four different types of chromosomal mutations: Deletions, Translocations, Duplications and Inversions (pictured below). Note that any chromosome mutation resulting in a significant loss of genetic material (Deletion) is most likely to be lethal.
