Document Summary
Lecture 16 characterisics that make drosophila an atracive model system. Know a lot about the geneic structure main stages in drosophila embryonic development. In lies the cell doesn"t divide with the nucleus (many nuclei in the same cell) Nuclei migrate to edges and get captured by cell membrane. *one genome creates two organisms main role of maternal efect, segmentaion and homeoic genes in drosophila development. Maternal-efect genes are transcribed in the mother but translated in the ofspring o. Segmentaion genes: when its in the middle and they divide the gene into segments o o o. Change the idenity of a segment structure/funcion of the homeobox in homeoic genes signiicance of evoluionary conservaion of hox genes. Occur along the chromosome in the same order they are expressed mechanism of plasmid toxin/anitoxin system as a possible origin for cell death genes. funcion of caspases. programmed cell death cascade in c. elegans.
