Mutations are typically simple errors in the nucleotide sequence of replicating DNA

Mutations are typically simple errors in the nucleotide sequence of replicating DNA. Despite potentially effecting only one of maybe thousands of nucleotides, this small error can distinctly change the structure and function of a protein. Considering the process of protein synthesis and the use of Codons during translation, explain how a single nucleotide error can have such an impact. (150-250 wds.)
