1. Objective: Understand the function of DNA
Key words: Nucleic Acids, DNA, RNA, nucleotides, nitrogen bases.
Nucleic acids are macromolecules (big molecules) containing hydrogen, oxygen, nitrogen, carbon, and phosphorous.
Nucleic acids are made of basic units called nucleotides.
Nucleotides consist of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base.
Individual nucleotides can be joined by covalent bonds to form a nucleic acid.
The structure of DNA is a double helix
Nucleic acids store and transmit hereditary, or genetic, information.
There are two kinds of nucleic acids: ribonucleic acid (RNA) and deoxyribonucleic acid (DNA)
As the name indicates, RNA contains the sugar ribose and DNA contains the sugar deoxyribose.
