You would like to amplify the gene shown below using PCR.  What is the sequence of the primer you would generate for the left side of the sequence? a) 5’ GCGGTTAA 3’ b) 5’ CGCCAATT 3’ c) 5’ TTAACCGC 3’ d) 5’ AATTGGCG 3’

In the protocol for extracting DNA, what is the purpose of the clear shampoo in the DNA extraction buffer? In the protocol for extracting DNA, what is the purpose of the clear shampoo in the DNA extraction buffer? Shampoo contains detergents, that help to break down lipids in cell walls, thus freeing the DNA. Shampoo contains detergents, that help to break down proteins in cell membranes, including the nuclear membrane, thus freeing the DNA. Shampoo contains salts, that help to break down lipids and proteins in cell membranes, including the nuclear membrane, thus freeing the DNA. Shampoo contains detergents, that help to break down lipids in cell membranes, including the nuclear membrane, thus freeing the DNA.
