DNA Backbone Structure • Alternate phosphate and sugar (deoxyribose), phosphate ester bonds
DNA Backbone Structure • Alternate phosphate and sugar (deoxyribose), phosphate ester bonds
DNA Primary Structure Summary • Backbone (sugar+phophate with phosphate ester bonds and base or heterocyclicamine side chains
DNA Double Helix • Base pairing by unique hydrogen bonds • C - G and A - T pairs
DNA Double Helix • Base pairing by unique hydrogen bonds • C - G and A - T pairs
DNA Replication • Polymerase enzymes which guide replication
DNA Replication • Polymerase enzymes which guide replication
DNA Replication • Complementary base pairs form new strands.
RNA Transcription • In nucleus, DNA guides the synthesis of mRNA
RNA Transcription • RNA polymerase and elongation reaction
RNA Transcription • RNA polymerase and elongation reaction
Types of RNA • mRNA contains codons which code for amino acids.
Types of RNA • rRNA - Ribosome - contains enzymes and keeps everything together
Types of RNA • tRNA - Transfer RNA carries amino acid and read codons on m-RNA through its own anticodons.
