Control, genomes and environment (F215)
  1. DNA - translations, mutations and coding
    1. Genes code fo polypeptides including enzymes.
      1. The sequence of the bases on a gene is a code with instructions for the construction of proteins. It had a no. of characteristics:
        1. It has a triplet code - 3 bases of an amino acid
          1. It is a degenerate code - All amino acids but one has more than one code.
            1. it is widespread but not universal - Codons generally always code for the same amino acid in every organism but it is not always the case.
            2. Transcription is the creation of a single-stranded mRNA copy of the DNA coding strand.
              1. The lac operon
