Episode 33 recAPs genetic engineering techniques of biotechnology. Electrophoresis separates molecular fragments according to size and charge visually (1:00). PCR amplifies DNA fragments, making thousands of copies from even the smallest sample (2:35). Bacterial transformation introduces foreign DNA into bacterial cells (4:00). DNA sequencing is a part of biotechnology, but typically not working with an entire genome at one time (6:15).The Question of the Day asks (8:08) “Which cells in the human body do NOT contain nuclear DNA?Thank you for listening to The APsolute RecAP: Biology Edition!(AP is a registered trademark of the College Board and is not affiliated with The APsolute RecAP.
