In this video I'll continue teaching you about DNA and RNA (nucleic acid chemistry), beginning with my showing you how physical traits are passed on through DNA replication. I'll go on to teach you about transcription (DNA to mRNA) and translation (mRNA to tRNA to peptide/protein), and how these processes are used to actually form proteins from the information encoded in our DNA. And I'll conclude by teaching you about the polymerase-chain reaction (PCR). Many thanks to FreeScienceLectures.com for their video on DNA replication (see http://www.youtube.com/watch?v=teV62zrm2P0&feature=related), as well as to the DNA Learning Center for my use of their highly awesome educational videos on DNA replication (see http://www.youtube.com/watch?v=4jtmOZaIvS0), transcription (see http://www.youtube.com/watch?v=5MfSYnItYvg), and translation (see http://www.youtube.com/watch?v=8dsTvBaUMvw). Whew! --Dr. Mike Christiansen from Utah State University.
