Question

Which of the following is not a part of DNA extraction?

a. Separate DNA from protein and debris
b. Isolate concentrated DNA
c. Collect cheek cells
d. Add enzymes to make the DNA "sticky"
e. Burst cells open

Answer 1

D

Step-by-step explanation:

Extracting DNA involves firstly harvesting the required cells (such as from the inside of cheeks), then the cells are broken up using enzymes or detergents. The products (usually a mixture of cell products –mainly RNA, DNA, and proteins) are then put in a centrifuge to separate the proteins from the DNA.
