Verified step by step guidance

Identify the original DNA sequence: 5' AAGCTTGC 3'.

Identify the mutated DNA sequence: 5' AAGCTTTGC 3'.

Compare the original and mutated sequences to determine what change has occurred. Notice that an extra 'T' nucleotide has been added in the mutated sequence.

Understand that the addition of one or more nucleotides into a DNA sequence is known as an 'Insertion' mutation.

Conclude that the mutation type is 'Insertion' because a nucleotide has been added to the original sequence.
