IV. Nucleic Acids- Informational Polymers A. Gene 1. determines amino acid sequence of polypeptide 2. consists of DNA- part of nucleic acids B. Store and Transmit Hereditary Info 1. enable living organisms to reproduce their complex components from one generation tot he next 2. DNA (deoxyribonucelic acid) a. provides directions for its own replication b. directs RNA synthesis c. through RNA controls protein synthesis d. is the genetic material that is inherited e. programs cell activities 3. RNA (ribonucelic acid) a. each gene along the length of the DNA molecule directs the synthesis of mRNA -> directs production of polypeptide b. protein synthesis occur at ribosome in cytoplasm C. Nucleic strand is a polymer of nucleotides (composed of an organic molecule [nitrogenous base], a pentose, and a phosphate grp) 1. Nitrogenous bases a. pyrimidine - six membered ring of carbon and nitrogen atoms. Cytosine, thymine, and uracil
