Maternal-effect genes and segmentation genes: segmenting the body: a (cid:374)u(cid:373)(cid:271)e(cid:396) of ge(cid:374)es (cid:272)o(cid:374)t(cid:396)ol the esta(cid:271)lish(cid:373)e(cid:374)t of the e(cid:373)(cid:271)(cid:396)yo"s (cid:271)ody pla(cid:374), these genes regulate the expression of other genes, two classes, maternal-effect genes and segmentation genes, work sequentially (figure. 2. different types of mutations in protein coding genes. 3. likely effect of various types of mutations on gene expression. 4. given the genetic code, identify mutations as missense, nonsense, or silent. 5. characteristics that make drosophila an attractive model system. 7. main role of maternal effect, segmentation and homeotic genes in drosophila development. 10. mechanism of plasmid toxin/antitoxin system as a possible origin for cell death genes. 13. possible evolutionary origin of programmed cell death genes. 13. role of programmed cell death in drosophila development. 3. reasons why identical twins may have different cancer incidence. 4. reasons why cancer mortality varies across geographical areas in canada. 8. role of proto-oncogenes, tumor suppressor genes and oncomirs in normal organismal metabolism/development. 9. mechanisms by which a virus could cause cancer without causing mutation.
