DNA DNA, deoxyribonucleic acid

DNA is a Nucleic Acid Nucleic acids are information storage molecules. They provide the directions for building proteins. Transcription Translation

Two strands of DNA join together to form a double helix.

Nucleotide monomers are linked into long chains. These chains are called polynucleotides, or DNA strands. A sugar-phosphate backbone joins them together.

Nucleic acids are polymers of nucleotides.

Two strands of DNA join together to form a double helix. Base pairing: A-T G-C
