RNA nucleotide base pairings - Cytosine (C) pairs to Guanine (G) Adenine (A) pairs to Uracil (U) DNA Sructure - because of this complementary base pairing, the order of the bases in one strand determines the order of the bases in the other strand Griffith's Experiment - in the 1920's, Frederick Griffith worked with two strains of Streptococcus pneumoniae bacteria. It was discovered that DNA was transmitted between the toxic and the harmless bacteria. DNA - -deoxyribonucleic acid -store...
