WebThe steps of the lesson are listed below. 1. Students watch a video about how PCR is performed and describe it. 2. Students perform "PCR" by writing in the complementary strand to each side of a split DNA. 3. Students use "restriction enzymes" to cut a DNA strand and count the number of nucleotides in each piece. 4. WebProtein electrophoresis is the process of separating samples of proteins based on size. With electrophoresis, proteins travel through a gel matrix, inside a small box, which is usually used in ...
