BIOL 3153 Study Guide - Comprehensive Final Exam Guide - Amplitude Modulation, Mesoderm, Endoderm
Document Summary
Biohomology patterns that are the same in a group of species. Concept 1: embryonic development involves pattern formation, pattern formation is the process of development by which cellular activity is organized so that a well structured embryo develops, early pattern formation growth patterns remain the same/proportions change. Concept 2: cell behavior is important, cell-cell signaling and cell migration. Concept 3: gene expression changes as an embryo develops, transcription factors can turn on/off a gene, our environment can influence gene expression. Concept 5: induction cell signaling that affects the development of another cell. Concept 6: genes provide instructions, but the embryo is the architect, rna in the egg from mum influences development, cell signaling during development as well as the environment influence development. Fertilization: restores diploidy by transmitting parents genes to offspring, initiates development by activating the egg, fusion of egg and sperm.
