RNA Transcription • In nucleus, DNA guides the synthesis of m. RNA

RNA Transcription • RNA polymerase and elongation reaction

RNA Transcription • RNA polymerase and elongation reaction

Types of RNA • m. RNA contains codons which code for amino acids.

DNA

Types of RNA • r. RNA - Ribosome - contains enzymes and keeps everything together

Types of RNA • t. RNA - Transfer RNA carries amino acid and read codons on m-RNA through its own anticodons.
