Name Date Hour Notes: Unit 1—Nucleic Acid
(1) What is a nucleic acid? Type of Biomolecule Means: Acid stored in the nucleus –Not all organisms store their nucleic acid in a nucleus –Eukaryotic = Nucleic Acid in Nucleus –Prokaryotic = Nucleic Acid NOT IN Nucleus
(2) Elements Carbon (C) Hydrogen (H) Oxygen (O) Nitrogen (N) Phosphorus (P)
(3) Monomer Nucleic Acid Monomer: –Nucleotide
(4) Polymer Nucleic Acid Polymer: –DNA –RNA
(5) Types of Nucleic Acids DNA = DeoxyriboNucleicAcid –Double Stranded Helix –Sugar in Nucleotide = Deoxyribose –Nitrogenous Bases = A, T, G, C RNA = RiboNucleicAcid –Single Stranded Helix –Sugar in Nucleotide = Ribose –Nitrogenous Bases = A, U, G, C
(6) Function Major: –Contains Genetic Information & Heredity –Contains Instructions to make cells function –Contains Instructions for making Proteins Minor: –There is no MINOR function. –IT’S YOUR DNA!!
(7) Examples All living cells contain DNA! Bacteria Protozoa from Pond Water Your Cells Fruits and Vegetables DNA Requirements: –Phosphorus –Sugar –Nitrogen
