Resource summary

genes
  1. expression highly regulated
    1. the functional unit that codes for a particular protein
      1. regulatory region called the promoter
        1. used to control when/how much of the gene is transcribed
          1. includes a terminator that tells polymerase when to stop transcribing
          2. transcription factors can have both possitive and negative control on transcription
            1. Operon
              1. a series of genes that are transcribed at the same time in one multi-gene mRNA and are controlled by the same promoter
                1. common in prokaryotes
