A point mutation might result in the formation of the codon TGA along the coding strand of DNA.
A point mutation is a type of mutation in which a single nucleotide in a strand of DNA is changed. This can occur due to errors during DNA replication or exposure to mutagenic agents, such as radiation or certain chemicals.
In the case of a point mutation, the change in a single nucleotide can affect the sequence of codons along the coding strand of DNA. A codon is a sequence of three nucleotides that encodes a specific amino acid or a stop signal for protein synthesis.
If a point mutation occurs in the middle of a codon, it can change the sequence of the codon and alter the amino acid that is encoded. For example, if a point mutation changes a G nucleotide to an A nucleotide in the codon GGA, the resulting codon will be TGA. This will change the amino acid encoded by the codon from glycine to cysteine.
In this way, a point mutation can result in the formation of the codon TGA along the coding strand of DNA. This type of mutation has the potential to affect the structure and function of the protein that is produced, depending on the location and nature of the mutation.
