Please review Genetics Unit Lesson 2 to learn how DNA copies itself. Note the complex molecular machinery required to simultaneously copy DNA in both the 5′ to 3′ direction, as well as in the 3′ to 5′ direction. For more on the mechanism, read about Okazaki fragments.
Remember, the Biology Task was due yesterday, so please see me if you have not yet submitted your final draft. Also, the DNA transcription project is due this Friday.
