To understand transcription and translation, Professor Wolfe states that you must first understand the “central dogma” that DNA makes RNA and RNA makes proteins. But how is this infromation communicated? Through transcription, which is the process where DNA information is coded into RNA, and translation which is the process of converting the mRNA molecule by ribosome into polypeptide strand. This process happens in both prokaryotic and eukaryotic cells, but in Eukaryotic cells translation takes place outside of the nucleus. Professor Wolfe also discusses the three different types of RNA, mRNA, tRNA, and rRNA. He explains rRNA and how is used to help translate the mRNA.
This lesson is perfect for review for a CLEP test, mid-term, final, summer school, or personal growth!
Taught by Professor George Wolfe, this lesson was selected from a broader, comprehensive course, Biology. This course and others are available from Thinkwell, Inc.

George Wolfe brings 30+ years of teaching and curriculum writing experience to Thinkwell Biology. His teaching career started in Zaire, Africa where he taught Biology, Chemistry, Political Economics, and Physical Education in the Peace Corps. Since then, he’s taught in the Western NY region, spending the last 20 years in the Rochester City School District where he is the Director of the Loudoun Academy of Science.
Besides his teaching career, Mr. Wolfe has also been an Emmy-winning television host, fielding live questions for the PBS/WXXI production of Homework Hotline as well as writing and performing in “Football Physics” segments for the Buffalo Bills and the Discover Channel.
His contributions to education have been extensive, serving on multiple advisory boards including the Cornell Institute of Physics Teachers, the Cornell Institute of Biology Teachers and the Harvard-Smithsonian Center for Astrophysics SportSmarts curriculum project. He has authored several publications including “The Nasonia Project”, a lab series built around the genetics and behaviors of a parasitic wasp.
He has received numerous awards throughout his teaching career including the NSTA Presidential Excellence Award, The National Association of Biology Teachers Outstanding Biology Teacher Award for New York State, The Shell Award for Outstanding Science Educator, and was recently inducted in the National Teaching Hall of Fame.
