Document Summary
All species share common genes and cellular functionalities. Tends towards homeostasis-homeostasis: maintenance of a relatively constant internal environment. 6 kingdoms prokaryotes - eubacteria & archaea. Body composition: average 70 kg human is 65% water. All major biopolymers have a substantially carbon backbone. Carbon compounds are relatively inert or kinetically stable to hydrolysis and oxidation. In general-organic reactions tend to be under kinetic control rather than thermodynamic control. Means thy are often favourable but slow and goof targets for enzymatic control. Biopolymer: a polymeric substance occurring in living organisms. Each cell uses a subset of expressed genes to achieve its structure and functions. Complete genetic information= genome - the complete genetic composition of a cell or species. Nb only known archea were separated from bacteria when began sequencing genes. The transcriptome (the rna)-the set of all rna molecules in one cell or a population of cells.
