Different types of mutations can occur in dna the diagram above represents a type of mutation which statement describes a mutation in the diagram?
a) a silent mutation results in the insertion of a different amino acid
b) a substitution occurs in the adenine base
c) a deletion of a cytosine base occurs
d) a base is inserted into one strand of the dna

D

Explanation:

When you count the number of bases after the mutation in the strand, you discover an additional one base(Adenine). Addition and deletion mutations are more likely to be lethal than substitution mutations. This is because the latter mutations cause a frameshift mutation that will disrupt the codon sequences downstream of the mutation. Ultimately, this largely affects the amino acid sequence of the translated protein, its properties, and how it folds (all which relate to and affect its function).

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
