CMMB 403 Final Exam Actual Questions and Answers with complete solution 72 hours (8 cells) (BEFORE BLASTOCYST STAGE) - answerwhat is the human MZT Mid-blastula transition/maternal-zygotic transition - answerwhen 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 fertilizat...

CMMB 403 Final Exam Questions With Correct Answers What are the origins of the optic vesicle and the lens? - answeroptic vesicle = forebrain (neural ectoderm) lens = surface epidermis --> placode Describe the process of lens induction - answer1. 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 into contact w/ the optic vesicle) ...
