Answer 1

Translation is the process of protein synthesis, codons are three-nucleotide sequences in mRNA, and stop codons signal the termination of protein synthesis. Mutating the stop codon can affect the protein sequence and function. The given DNA sequence transcribes to an mRNA sequence and amino acid sequence.

Step-by-step explanation:

Translation is the process by which the information in mRNA is used to synthesize a protein. It occurs in the ribosomes of the cell.

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or a stop signal during translation.

A stop codon is a specific codon (UAA, UAG, or UGA) that signals the termination of protein synthesis.

If the stop codon was mutated to encode for another amino acid, the protein synthesis process would not be terminated at the intended point, resulting in an altered protein sequence which may affect its structure and function.

The mRNA sequence transcribed from the given DNA sequence 'ATGTTAGCCGTATGC' would be 'AUGUUAGCCGUAUGC'.

The corresponding amino acid sequence would be 'Met-Val-Ala-Val-Cys'.
