CMMB 403 Final Actual Questions and CORRECT Answers 72 hours (8 cells) (BEFORE BLASTOCYST STAGE) - CORRECT ANSWER- what is the human MZT Mid-blastula transition/maternal-zygotic transition - CORRECT ANSWER- when the transcription of zygotic genes begins and maternal mRNAs are degraded, the cell cycle lengthens, gap stages are added (before is only M and S) and the synchronicity of cell division is lost. - embryo runs on maternal resources (mRNAs and proteins in the egg @ time of fe...

CMMB 403 Final UPDATED Actual Questions and CORRECT Answers What are the origins of the optic vesicle and the lens? - CORRECT ANSWER- optic vesicle = forebrain (neural ectoderm) lens = surface epidermis --> placode Describe the process of lens induction - CORRECT ANSWER- 1. the optic vesicle (forebrain) induces thickening of the surface epidermis (prospective lens placode) 2. the optic vesicle pinches in to form the optic cup and the lens invaginate as well (lens placode comes i...

CMMB 403 Midterm 1 Question and answers 100% correct CMMB 403 Midterm 1 Describe the RTK signal transduction pathway when activated by the FGF ligand FGF ligand dimerizes RTK receptor. Receptor is phorphorylated and attracts adaptor/GEF. GEF begins phosphorylation cascade: GEF to Ras to Raf to Mek to Erk to TF. TF transcribes gene Describe the JAK-STAT pathway when activated by FGF FGF ligand dimerizes RTK. JAK2 proteins cross-phosphorylate. Both JAK2s phosphorylate a STAT5 (which is...
