Question

is the mutation classified as a point or frameshift mutation? point

6 original dna sequence 2: aaa ttc ccg ggg
mutated dna sequence 2: aaa ttg ccc ggg

is the mutation an insertion, deletion, or substitution? ______
is the mutation classified as a point or frameshift mutation? ______

Explanation:

Original DNA: AAA TTC CCG GGG; Mutated DNA: AAA TTG CCC GGG. The second codon TTC → TTG has a single nucleotide change (C→G), which is substitution. Substitution affects one nucleotide, classifying it as a point mutation (no frameshift).

Answer:

substitution, point mutation
