Document Summary
E coli- model for dna replication, protein production. Brewer"s yeast- reproduce quickly, so a model for cell division cycle. Arabidopsis plant- development and physiology of crops, evolution. Solution- multiple origins of replication, start at different times. Prokaryotes lack a nucleus or other intracellular compartments. Mitochondria and chloroplasts thought to have endosymbiont origins- have their own dna and a double membrane. Acids- release protons when dissolved in water, forming h3o. Bases- accept a proton when dissolved in water, [oh-] 2 monosaccharides can be linked by a glyosidic bond, forming a disaccharide. This is a condensation reaction that expels a mo lecule of water as the bond is formed. Can be broken by hydrolysis, consume an h2o molecule. Have a carboxylic acid group and an amino acid group, linked to alpha carbons. Peptide bonds form between amino acids through a condensation reaction. Can act as short term carriers of energy- atp. The 3 phosphates of atp are linked by phosphoanhydride bonds.
