Question

down).
part 1:

1. look at the rna strands provided. note: each rna has an \original\ strand on top and a \mutated\ rna strand on bottom.
2. decide which of the strands show a substitution mutation, insertion mutation, deletion mutation and write your answers below.
3. give one piece of evidence that supports the type of mutation you chose

chart with rna strands and mutated rna strands as described in the text

Explanation:

• RNA 1: Deletion mutation. Evidence: The mutated RNA 1 has one less nucleotide (the first 'U' in original RNA 1 is missing in mutated RNA 1).
• RNA 2: Substitution mutation. Evidence: In the 8th position, 'U' in RNA 2 is replaced by 'A' in mutated RNA 2.
• RNA 3: Insertion mutation. Evidence: There is an extra 'A' in mutated RNA 3 compared to RNA 3.
• RNA 4: Insertion mutation. Evidence: There is an extra 'G' in mutated RNA 4 compared to RNA 4.

Answer:

• RNA 1: Deletion mutation. Evidence: One - nucleotide deletion.
• RNA 2: Substitution mutation. Evidence: Nucleotide substitution at position 8.
• RNA 3: Insertion mutation. Evidence: One - nucleotide insertion.
• RNA 4: Insertion mutation. Evidence: One - nucleotide insertion.
