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...

where does transcription occur correct answer: nucleus (of eukaryotes) where does translation occur correct answer: the cytoplasm 3 steps in translation correct answer: 1. initiation 2. elongation 3. termination initation correct answer: - Brings all the translation components together - Initiation factors assemble ribosome components - Small ribosomal subunit, initiator tRNA, and the large ribosomal subunit - The initiator tRNA attaches to the start codon (AUG) - The ribosome...
