During genomic DNA isolation, we usually denature proteins using
A. Phenol/chloroform
B. Ethanol
C. Proteinase
D. Detergent
Homework Answers
Answer (A)
For DNA extraction some procedure needed to follow that is precipitation,washing and resuspension.phenol/chloroform are used to denature the protein.These use in precipitation.phenol and chloroform denatured the protein and dissolves denatured protein.
