The New Product Development process is often referred to as The Stage-Gate innovation process, developed by Dr. Robert G. Cooper as a result of comprehensive research on reasons why products succeed and why they fail.
Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size. In gel electrophoresis, the molecules to be separated are pushed by an electrical field through a gel that contains small pores. The molecules travel through the pores in the gel at a speed that is inversely related to their lengths.
Gel electrophoresis and DNA. 1  Electrophoresis enables you to distinguish DNA fragments of different lengths. 2  DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode.
