GENE FUNCTION DNA: A gene is a portion of a DNA molecule DNA extends the length of the chromosome DNA contains four bases – adenine, thymine, guanine, cytosine The different sequences of bases = gene Ave. gene ~ 600 consecutive bases RNA: Each gene controls the production of one or more RNAs RNA “translates” the genetic code to protein production 3 GENE FUNCTIONS: 1. Self duplication – duplication is exact 2. Production of RNA: The gene (or a portion of a gene) serves as a template for the formation of an RNA The RNA passes from the nucleus to the ribosome and provides directions for the formation of a specific protein 3. Protein synthesis – Genes contain the blueprints for ALL proteins GENE Î RNA Î protein (hormone, enzyme, etc) ÎÎ specific event SEQUENTIAL REACTIONS: Body functions require numerous (thousands) of biochemical reactions to reach their conclusion. Each reaction requires one or more genes to create the enzyme, hormone, etc. needed to drive the reaction Each Reaction must follow a specific
