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
                1. Genes and body plans
                  1. Apoptosis
                    1. Meiosis and the significance
                      1. Genetic diagrams
                        1. Gene loci
                          1. Determining sex
                            1. Population gentics
                              1. Role of genes and environment
                                1. What is a species?
                                  1. Selection
