    During translation, Ribosomal RNA combines with proteins to form a ribosome. tRNA (transfer RNA) brings individual amino acids to the ribosome, mRNA binds the ribosome. 3 nucleotides at a time equal 1 codon or an amino acid. Therefore the resulting amino acid sequence from the previous mRNA is AUG, GGA, AAU, CAU, CGG, UGA = Methionine, Glycine, Asparagine, Hisitdine, Proline, Stop. The first codon of the sequence (AUG), is the start of the sequence. The significance of this codon is that it symbolizes where the mRNA should start copying. The last codon of the sequence (UGA) is the end of the sequence or mostly known as "Stop". This symbolizes where the mRNA should stop copying.…
