Species Binomial System of Nomenclature Two words: genus + species ex: Homo sapiens Homo erectus Bacillus anthrax The Cell All organisms are composed of cells. The cell is the lowest level of structure capable of performing all the activities of life. All cells are enclosed by a membrane and contain DNA. Two major kinds of cells: Prokaryotic Cells (bacteria) Eukaryotic Cells The Inheritance of Biological Information (DNA) Biological instructions maintain order and control the properties associated with life. These instructions are encoded in molecules of deoxyribonuncleic acid (DNA). Genes are the units of inheritance that are passed from parents to offspring. Genes are made of DNA. DNA is duplicated and distributed during reproduction. Genome refers to an organism's total genetic material (all of the genes or DNA) Human genome= all the DNA in a human cell...
