RNA Transcription
• RNA polymerase and elongation reaction
Types of RNA
• mRNA contains codons which code for amino acids.
DNA
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.
