A mutation.
A point mutation, specifically a substitution mutation, is when only one nucleotide base is altered in a gene sequence, affecting one codon. This can result in a change in the amino acid encoded by that codon in the mRNA, impacting the protein produced by the gene.

The nucleotide sequence of one gene can differ significantly from that of an entirely different gene due to variations in the order of the nucleotides. These differences in sequence are the basis for the diversity of genetic information that allows for functional specialization of genes and the expression of different traits. Genes that code for different proteins or perform distinct functions will have distinct nucleotide sequences.
Extra long proteins are likely to fold improperly and not function correctly. The overall health of the individual would be destroyed.

A gene, because any smaller and it would just be nucleotides.
A mutation that involves a single nucleotide is called a point mutation. This type of mutation can include substitutions, insertions, or deletions of a single nucleotide in the DNA sequence.

These differences in sequence are the basis for the diversity of genetic information that allows for functional specialization of genes and the expression of different traits. Genes that code for different proteins or perform distinct functions will have distinct nucleotide sequences.
The three main types of gene mutations are point mutations, insertion mutations, and deletion mutations. Point mutations involve changes to a single nucleotide base. Insertion mutations involve the addition of extra nucleotide bases. Deletion mutations involve the removal of nucleotide bases in a gene sequence.
