SUMMARY
Transcription:First, the RNA Polymerase binds and unwinds the DNA molecule. Second,
RNA Polymerase binds to the promoter region of DNA. The, RNA Polymerase reads DNA and create the mRNA strand. Next, RnNA Polymerase this stop the stop codon and releases the mRNA. Last, mRNA leavs the nucleus and enter the cytoplasm.
Translation:First, rRNA formed the ribosome. Second, mRNA binds to the
ribosome. Next, tRNA brings in the anti-codon. Then, amino acids attach to tRNA and then bind with a peptide bond. Last, the ribosomes hit the stop codon and complete the protein.
