Document Summary
Biochemistry is the study of the chemistry of life processes. Main classes of molecules are: biological macromolecules (these include proteins and nucleic acids, metabolites (this is glucose and glycerol or any low molecular weight molecule) Observations of similarities between organisms at the molecular level (metabolic processes) suggest that all living things have a common ancestor. The three domains of life are: eukarya (all multicellular organisms and some unicellular microscopic organisms- well defined nucleus in each cell, bacteria (unicellular organisms that lack a nucleus, archaea. 1. 2: dna illustrates the interplay between form and function. All cellular organism have dna that is used to store genetic information. Dna is made up of four building blocks (monomers). It has a backbone made of repeated sugar- phosphate units. The sugars are deoxyribose and each one is connected to two phosphate groups on each side. Each sugar is also connected to one of the four bases:
