What happens if the first A is removed from the mRNA sequence CCAGGCUUACCG?
Understand the Problem
The question is asking about the effect of removing the first 'A' from a given mRNA sequence on the resulting codons and reading frame. The user needs to evaluate the consequences of this deletion mutation.
Answer
The reading frame would shift and the new codon would read CCG.
The reading frame would shift and the new codon would read CCG.
Answer for screen readers
The reading frame would shift and the new codon would read CCG.
More Information
Removing a nucleotide causes a frameshift mutation, altering every subsequent codon.
Tips
A common mistake is assuming that frameshift mutations only affect the nearest codon.
