WHAT ARE NUCLEIC ACIDS? • Polymers consisting of monomers called nucleotides. • Two types – DNA: Deoxyribonucleic Acid – RNA: Ribonucleic Acid • The reason why you may share common characteristics with your biological parents. • The reason why multiple generations of flowers may look the same or different. • The reason why diseases and disorders run in certain families. • The reason you look like… you! • AND SO MUCH MORE!!!

NUCLEOTIDES • Nucleotides are the monomers (subunit/ building block) of nucleic acids. • Each nucleotide consists of: 1) A Phosphate group 2) A sugar 3) A nitrogenous base

2 TYPES OF NUCLEIC ACIDS 1) DNA 2) RNA

1) DNA Deoxyribonucleic Acid Stores genetic (inheritable) information DNA tells each cell which proteins to make and how to make them. • Made up of a DOUBLE HELIX (two coiled strands) of nucleotides. • Looks like a twisted ladder. • The support beams are called the “sugar-phosphate backbones. ” • Contains the sugar Deoxyribose. • Contains the Nitrogenous Bases: • Adenine (A), Cytosine (C), Guanine (G), and Thymine (T).

2) RNA Ribonucleic Acid Contributes to the production of proteins in a cell. It’s

2) RNA Ribonucleic Acid Contributes to the production of proteins in a cell. It’s like a messenger between DNA and the “protein factory. ” • SINGLE STRAND of nucleotides • Contains the sugar Ribose. • Like DNA, it has a Sugar. Phosphate backbone. • Contains the Nitrogenous Bases: • Adenine (A), Cytosine (C), Guanine (G), and Uracil (U).
