During the process of transcription, a nucleotide was deleted from an mRNA sequence that coded for a protein. What effect will this deletion have on the amino acid sequence of the protein?
What will be an ideal response?
Deletion of a base during transcription will change the makeup of all subsequent codons in the mRNA base sequence. The altered mRNA sequence will then result in the inclusion of a different series of amino acids into the protein during translation. Almost certainly the protein so produced will not be functional.
