DNA ISOLATION FROM AGAROSE GELS WITH DEAE PAPER
... After the DNA bands have been separated electrophoretically (at around 80 V), the gel is viewed under long wave UV light and a slit cut in the gel, just ahead of the desired band. A piece of DEAE paper is inserted in the slit. Another piece of DEAE paper can be inserted behind the desired band, to p ...

The Functions of Introns: From Junk DNA to Designed DNA
... All genes begin with exons (the protein-coding segments), but most have a variable number of introns within them that alternate with the exons. Introns were discovered in 1977 as a result of observing that the mRNA used to code for proteins was almost always shorter than the DNA from which it had be ...
