Document Summary
This isn"t really precise in the general region of. In the white part of the eye, the gene was turned off but in red parts, the gene had been turned on somehow. Where the genes are determine the expression of the genes depending if in heterochromatin regions. The expression of sequence depends on the location (reason you don"t see anything is because it is in a place that it cannot be expressed) You get mutations by an active process; damage by itself versus the cell doing something to make a mutation mutagenesis. Mispair --> need to see if there is still time to fix this. This would be considered a point mutation (single based substitution) maybe in a region which no critical info silent mutations (no gene expressed), maybe the third position of the codon (where the change is) Missense mutations: change the information (conservative change: converse the type of amino acid based on polar, nonpolar, etc. )
