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...

Species - group of individuals with the potential to interbreed and produce viable offspring *some asexual organisms are recognized as species although they do not breed. archaebacteria - microorganisms that are similar to bacteria in size and simplicity of structure, but radically different in molecular organization. now believed to constitute an ancient intermediate group between the bacteria and eukaryotes prokaryote - a single celled organism that has neither a distinct nucleus with a m...
