  15. Protein Synthesis http://www.youtube.com/watch?v=NJxobgkPEAo The base pairs: Adenine to Thymine (uracil in RNA) Guanine to cytosine

  16. Transcription and translation • Transcription: The code in the DNA is converted to a messenger RNA (mRNA) strand. • Takes place in the nucleus. • Translation: the process by which the message on the mRNA is converted to a protein: Takes place in the cytoplasm and uses ribosomes and transfer RNA (tRNA).
