MACROMOLECULES NUCLEIC ACIDS
2
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!!!
3
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
4
2 TYPES OF NUCLEIC ACIDS 1) DNA 2) RNA
5
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).
6
2) RNA Ribonucleic Acid SINGLE STRAND of nucleotides
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).
