Chapter 1: Biology and The Tree of Life  An organism is an entity made up of one or more cells  Characteristics of Life: 1. Cells: organisms are made up of membrane-bound units called cells. The membrane of a cell regulates the passage of materials between interior and exterior spaces 2. Replication: Everything an organism does contributes to one goal- replicating itself 3. Evolution: changing over time 4. Information: process hereditary, or genetic, information encoded in units called genes. Respond to outside stimuli 5. Energy: Acquire and use energy (plants absorb sunlight and animals ingest food)  Three of the greatest unifying ideas in science are the cell theory, the theory of evolution, and the chromosome theory of inheritance  A theory is an explanation for a very general class of phenomena or observations that are supported by a wide body of evidence  The cell theory describes how all organisms are made up of cells and how all cells come from preexisting cells  The theory of evolution is the process of how organisms change over time, natural selection  The chromosome theory of inheritance identifies chromosomes as the carriers of genetic materials  A hypothesis is a testable statement that explains something  An experiment allows researchers to test the effect on factors on particular phenomena  A prediction is a measurable or observable result that must be correct if the hypothesis is valid  A species is a distinct, identifiable type of organism  Evolution is a change in a population over time  A population is a group of individuals of the same species that live in the same area at the same time  Speciation occurs when populations make more species  Fitness is the ability of an individual to produce offspring  Adaptation is the trait that increases the fitness of an individual in a particular environment  Natural Selection: 1. Individuals must vary in characteristics that are heritable 2. Certain versions of these heritable traits help individuals reproduce more than oher versions  The Central Dogma: o The Central Dogma describes the flow of information in cells o A chromosome consists of a molecule of deoxyribonucleic acid (DNA) o DNA is a hereditary material o DNA is a double stranded helix o Genes consist of specific segments of DNA that code for products in the cells o Each strand of the double helix is made up of varying sequences of four different types of building block  A- adenine  T- thymine Pair together  G- guanine  C- cytosine Pair together o Molecular machinery in the cells makes a copy of a particular gene’s information in the form of a closely related molecule called ribonucleic acid (RNA) o RNA molecules determine what building blocks to use to make protein  Organism’s Fundamental Needs: o Acquiring chemical energy in the form of a molecule called adenosine triphosphate (ATP) o Obtaining molecules that can be used as building blocks for the synthesis of DNA, RNA, proteins, the cell membrane and other large, complex compounds required by the cell  The Tree of Life: o Used to understand the phylogeny of all organisms - their actual genealogical relationships o A diagram that depicts evolutionary history is called a phylogenetic tree o The sequence of building blocks in DNA is a trait that can change over the course of evolution o Researchers propose that the trees routes extend back to the “Last Universal Common Ancestor” (LUCA) o To draw trees researchers, use molecular biology, morphology, embryology, fossil records and evolutionary relationships o Groups of Organisms:  Bacteria  Archaea  Eukarya 3 Domains of Life o Eukaryotes= membrane bound nucleus o Prokaryotes= no nucleus (mostly bacterial and archaeal cells) o Taxonomy is the effort to name and classify organisms o Any group of organisms is called a taxon (plural: taxa) o Biologists use the word phylum (plural: phyla) to refer to major lineages within each domain o Phyla are categorized by distinctive body structures as well as gene sequence  Binomial Nomenclature: o Genus (plural: genera) is made up of closely related groups of species o Species is always preceded by its genus, regularly breed o Genus names are capitalized but species names are not, italicized (ex: Homo sapiens) o If you are writing the scientific name and cannot italicize, then underline the 2-part scientific name
