    Transcription is when RNA polymerase (enzyme) attaches to the DNA helix breaking the hydrogen bonds between the two strands. One strand is used as a template for a mRNA strand. RNA nucleotides join with the template strand and create a RNA strand. The hydrogen bonds in the DNA double helix reform and coil again. RNA leaves the nucleus. Translation is when the RNA attaches to a ribosome and tRNA carry amino acids to the ribosome. Anticodons on the tRNA that are complementary to the codon on the RNA attach and the amino acid on the tRNA begins the formation of a polypeptide chain. The ribosome moves along the RNA, allowing more tRNA molecules to add their amino acids to the chain, until a stop codon is reached and a protein is made.
