The genetic code I will discuss the genetic code, looking at the specific areas of transcription/translation, the codon/anticodon, mutation, sense/antisense, the non-overlapping codon and the intron. The genetic code is the base sequence of the DNA that has been copied to a base sequence in mRNA. "This sequence is the genetic code for a protein."1 This code is for a single amino acid, which is called a codon. The genetic code has two very important features. The first is a non-overlapping codon; this codon is a specific start codon, which ensures that the ribosome correctly 'read' the mRNA in a "unique way"1. This unique way is in sets of three, "64 triplets of nucleotides."3 For example: AUG AAU TCG CCU. The second feature is that the code is degenerate. This means some of the amino acids are coded for more than one codon. Transcription is the transfer of information from DNA to mRNA. The double stranded helix DNA...
