Map the following onto this image. These are kind of imprecise - PowerPoint PPT Presentation

Map the following onto this image. These are kind of imprecise arrows but I thought thinking about the different What stage of the protein making ways genes are regulated in this way process is affected when genes are would help! regulated through • epigene9c modifica9ons • transcrip9on factors • post transcrip9onal modifica9on DNA (RNA processing, RNA splicing) mRNA Ribosome Ribosome • microRNA Polypeptide Polypeptide • post transla9onal modifica9on

I did not use this next slide in class but last year a student said it was helpful. I used it when I taught conserva9on biology to non-majors-thus the candy! I find you all oWen have trouble with the concept of alleles so maybe this helps!

Image below shows 5 pairs of homologous chromosomes in 5 different individuals. Which other individuals are heterozygous at the gumball locus? Individuals “2” and “3” How many alleles are there in this popula1on of 5 individuals at the gumball locus? 3!
