Phenylalanine codon, deletion

Proteins are composed of chains of amino acids. In the genetic code of deoxyribonucleic acid (DNA), a codon or three-base sequence codes for the placement of each amino acid for example, the codon UUU places phenylalanine at that location in the protein and replacement of the third base with adenine results in the placement of leucine instead of phenylalanine. If a portion of the original code read. . . UUUACG. . . , deleting one of the uridine bases would cause that portion of the code to read. . . UUACG. .. the sequence UUA would then specify leucine. A point mutation changing one base might result in the formation of a different protein.
