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.

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.
