Verified step by step guidance1
Understand the concept of mutations: Mutations are changes in the DNA sequence that can affect genetic information. They can occur naturally or be induced by external factors.
Identify the types of mutations: Common types include inversion, deletion, substitution, and insertion. Each type affects the DNA sequence differently.
Define insertion mutation: An insertion mutation involves the addition of one or more nucleotides into the DNA sequence, which can alter the reading frame and potentially change the protein produced.
Compare insertion with other mutations: Inversion involves flipping a segment of DNA, deletion involves removing nucleotides, and substitution involves replacing one nucleotide with another. Insertion is unique because it adds nucleotides.
Recognize the impact of insertion mutations: Adding nucleotides can lead to frameshift mutations if the number of nucleotides added is not a multiple of three, affecting the downstream amino acid sequence during translation.
