To accurately identify the type of mutation that has occurred, I would need to see the diagram you're referring to, as the type of mutation (frameshift, substitution, deletion, or insertion) can often be inferred from visual representations of genetic sequences or structural variations.
However, I can provide a brief overview of each type of mutation:
-
Frameshift Mutation: This occurs when nucleotides are added or deleted from the DNA sequence in a number that is not a multiple of three. This shifts the reading frame of the codons in the sequence, potentially altering all amino acids that follow the mutation.
-
Substitution Mutation: This involves the replacement of one nucleotide with another. This can lead to a silent mutation, a missense mutation, or a nonsense mutation, depending on whether the change affects the amino acid sequence.
-
Deletion Mutation: This type of mutation occurs when one or more nucleotides are removed from the DNA sequence.
-
Insertion Mutation: This involves the addition of one or more nucleotides into the DNA sequence, which can also lead to frameshift mutations if the insertion number is not a multiple of three.
Please refer to the characteristics of the disorder presented in the diagram, and based on that, you can determine which type of mutation has caused it. If you can provide additional details about the mutation or disorder, I would be happy to help you identify it!
