This sequence encodes for a particular protein that helps bacteria move. A mutation occurs in the sequence, leading to a faulty protein. Identify the sequences where the mutation might have taken place.

The red letters are the noncoding region, and the black letters are the protein coding region.
To identify the potential sequences where the mutation might have occurred, we need to understand that the protein coding region is where the functional part of the protein is encoded, while the noncoding region does not directly contribute to the protein sequence.
Let's break down the given sequence into its individual codons, which are groups of three nucleotides that encode for a specific amino acid in the protein.
ATG-TGC-ATA-CTA-CCG-GGC
The codons are:
1. ATG - This is the start codon that initiates protein synthesis.
2. TGC - Encodes for an amino acid.
3. ATA - Encodes for an amino acid.
4. CTA - Encodes for an amino acid.
5. CCG - Encodes for an amino acid.
6. GGC - Encodes for an amino acid.
Since the mutation is said to lead to a faulty protein, we need to identify the codon(s) that have been altered. The mutation could occur in any of the individual codons.
To determine the potential sequences with mutations, we can compare each codon of the given sequence with the standard genetic code, which specifies which amino acid is encoded by each codon. If any of the codons have been mutated, i.e., the nucleotides have been changed, a different amino acid may be coded, leading to a faulty protein.
Here is the comparison of the given codons with the standard genetic code:
1. ATG - This codon encodes for the amino acid methionine (Met). No mutation is present.
2. TGC - This codon encodes for the amino acid cysteine (Cys). No mutation is present.
3. ATA - This codon encodes for the amino acid isoleucine (Ile). No mutation is present.
4. CTA - This codon encodes for the amino acid leucine (Leu). No mutation is present.
5. CCG - This codon encodes for the amino acid proline (Pro). No mutation is present.
6. GGC - This codon encodes for the amino acid glycine (Gly). No mutation is present.
Based on the comparison, there are no mutations found in the given sequence. Therefore, all the codons remain intact, and the protein should function normally.
