Describe the phylogeny of GRs? - ️️Bees. Only about 350 to 400 ORs. Ants have the record for ORs. Unlike honey bees, actually expansion in GRs (also true of Nasonia). Bees lost this shit, down to like 12. Basic pathway of RNAi - ️️1. double stranded RNA is recognized by an enzyme, dicer and cleaved into short piece abotu 21 bp long 2. These 21 bp long sections are recognized by a complex of proteins called RISC (RNA induced silencing complex) which uses them to recognize perfectly m...

Lecture 6: Vocab: ● Autosome: ○ Any chromosome not considered as a sex chromosome, or is not involved in sex determination. ○ It occurs in pairs in somatic cells and singly in sex cells (gametes) ● Bivalent: ○ a pair of homologous chromosomes. ● Drosophila melanogaster: ○ a species of fruit Fly much used in genetics because of the large size of its chromosomes. ● Epistasis (gene x gene interaction): ○ refers to genetic interactions in which one gene modifies the eff...
