Remember from the Genetics Unit…. Chromosomes. carry hereditary information (information that is passed to offspring) that is present in distinct units called . genes. arranged along chromosomes like beads. . 1-deoxyribonucleic acid (DNA). 2-Ribonucleic acid (RNA. Nucleic. Acids. Structure: Nucleotide. Monomer : . Nucleotide. A pentose sugar molecule .. 2.A phosphate group .. 3.A nitrogenous base .. Monomer : . Components of DNA. Sugar = Deoxyribose. Ribose is missing hydroxyl group (-. OH. ) from 2’C. Phosphate = PO. 4. 3-. Links to the sugar @ either its 3’C or its 5’C. Water (H. OH. ) is lost in the condensation reaction. pts. fill-in w/ . wordbank. (. Words from . today’s notes . not included). nucleus . DNA. Gene. Chromosome. Backbone. Base. Adenine. Guanine . Cytosine.
