In the DNA molecule, as a result of the thermal movement of atoms, one of the nucleotides (G) has turned into another (C). what might result?

Mutation.

Due to the replacement of the nucleotide, a point (or gene) mutation will occur. This can lead to the fact that the triplet, which includes this nucleotide, will encode a completely different amino acid. This, in turn, will lead to the synthesis of a completely different protein, which may be defective. Another option is that the replacement of the nucleotide will make a specific triplet a stop codon, that is, protein synthesis at this point will stop, the protein will be incorrect.

But there is a chance that there will be no such consequences. Due to the redundancy of the genetic code, a nucleotide substitution can replace a triplet with another encoding the same amino acid.
