MATH 221 Lecture 5: EXAM 1 REVIEW DEVELOP
Document Summary
Germ plasm theory was proposed by august wismon in 1891. The theory states it is the germ cells only that will give rise to a new organism. As the germ cells divide, they will form cells that will have half the number of cells. Roux did defect experiments and was trying to test the germ plasm theory. The transplantation experiments he used two glass plates and started at 8, added glass plates to presuize embryos, then removed pressure at 16 stage and he noticed regardless of distribution he formed ___ embryo. Chromatin is consists of dna wrapped around histones. High c g promoters and low cg promoters. 3-poly a tail: for stability, assists with mrna export, specifically the mature mrna transcript. 5 utr- starter sequences includes start codon and poly a tail is after: but cap itself is just 7 methylated guanine nucleotides. Focus on statemtns 3 and 4, explain on exam.
