Document Summary
Fertilized eggs will undergo embryonic development and will form 250 distinct types of differentiated cells. Some cells become part of the digestive gland, skeletal system and so forth. These specialized cells to be formed by differentiation depends on the signals it receives from the surrounding environment. These signals in turn depend on the position of the cell within the embryo. Differentiation results in different cells having unique appearances and containing unique materials. Skeletal muscle cells= filaments composed of contractile proteins. Despite these differences, these cells are composed of similar organelles. Representatives that are studied in order to provide a framework to understand basic processes shared by most organisms. Six model organisms (one prokaryote and five eukaryotes): e. coli. Basic molecular biology of the cell (mechanisms of replication, transcription and translation) was worked out on this organism: baker"s yeast. Contains many proteins that are homologous to proteins in human cells.
