• wound into chromosomes
• organization of dank (not inside)
• All living organisms have dna
• viruses might have rna
• is a macromolecule (1 of 4 body ones)
• Dna double helix
• 5 carbon sugar phosphate group
• nitrogenous bases
• nb's made of or purines or paremidens
• pyrimidines have 1 group (cytosine, thymine )
• purines have 2 groups (guanine, adenine)
• pyr cant match with pyr, pur cant match with pur
• c and g always paired
• a and t always paired
• bases joind by weak hydrogyn bond
• 3 major functions
• gene goding
• dna replication
• codes for proteins
• sequence of bases acts as information
• long to store more info
• way bases work  is vital bc allows to replete from either side
• weak hydrogen bonds allow for it to be zipped and unzipped easily
•
