Nucleic Acids and Lipids nucleic acids - information storage devices of cells; 2 varieties can serve as templates to create exact copies of themselves deoxyribonucleic acid (DNA) - the hereditary material ribonucleic acid (RNA) - used to read DNA in order to create proteins; used as a blueprint to create amino acid sequences finally able to be seen w/ scanning-tunneling microscope nucleotides - subunits of nucleic acids contains 5-carbon sugar, phosphate group, organic base purine - large, double-ring molecules; adenine, guanine (both in RNA/DNA) pyrimidine - smaller, single-ring molecules; cytosine (in RNA/DNA), thymine (in DNA only), uracil (in RNA only) DNA made of difference combinations of 4 types of nucleotides (adenine, guanine, cytosine, thymine) 2 chains wrap around each other like a staircase ( double helix shape) hydrogen bonds hold 2 chains together adenine only complementary to thymine (in DNA), uracil (in RNA) cytosine only complementary to guanine RNA
