Document Summary
Not as efficient as a mammalian system. Look at how the dna is wound around the histones (proteins) Make the amino acid tails bind more tightly to the dna by changing the sequence of functional groups that are put onto the tails. Methylate a diff amino acid and phosphorylate a diff amino acid. Both of these configurations have methyl groups. Which functional groups are attached to which amino groups. 70% of your gene are not being transcribed. When you have a methylated promoter, the gene is not going to be expressed. When it codes for one diff amino acid. Can be linked to a nonsense mutation. Polymerase will go in and fix it. Turns off mrna of completely degrade it. Diff protein products from the same gene. Thin wet surface for this to occur. Two males/ females trying to gain access to something. Intersexual selection: male trying to impress female (vice versa)
