DNALC Live: Join us Monday, April 6th at 1:00 PM EDT for a virtual lab! Jeff will extract DNA from snack foods in an effort to detect GMOs through PCR. Watch and download worksheets to follow along here:
In the early days of DNA manipulation, DNA fragments were laboriously separated by gravity. In the 1970s, the powerful tool of DNA gel electrophoresis was developed.
Leroy Hood explains the process of sequencing using an automated sequencing machines.
Rich Roberts and Phil Sharp explain restriction enzymes, electrophoresis, and split genes.
New York high school students perform the Alu polymorphism lab then interview Prof. Larry Kobilinsky at John Jay College of Criminal Justice about DNA fingerprinting.
New York high school students interview Dr. Scott Lowe of Memorial Sloan-Kettering Cancer Center about using restriction enzyme analysis in cancer research, then perform the experiment.
Learn how the cause of Xeroderma pigmentosum is caused by a defect in a DNA repair system.
Fred Sanger outlines DNA sequencing.
