In order to determine how many amino acids are likely impacted by a 31 nucleotide deletion in a DNA sequence, we need to know the reading frame of the gene. A reading frame is a way of grouping nucleotides into codons, which are then translated into amino acids.
Assuming that the reading frame is not disrupted by the deletion, the deletion of 31 nucleotides will result in a frameshift mutation. This means that all of the codons downstream of the deletion will be shifted by one nucleotide, resulting in a completely different amino acid sequence.
Since each codon is made up of three nucleotides, the deletion of 31 nucleotides will result in the loss of 10 codons (31 / 3 = 10.33, rounded down to 10). Therefore, if the reading frame is not disrupted, we can expect that the deletion of 31 nucleotides will result in the loss of 10 amino acids.
However, if the reading frame is disrupted by the deletion, the impact could be much greater. In this case, the deletion could result in a completely different amino acid sequence downstream of the deletion, which could have significant functional consequences for the protein encoded by the gene.
Therefore, without more information about the reading frame and the specific gene in question, it is difficult to say exactly how many amino acids will be impacted by a 31 nucleotide deletion.
