DNA Extraction

I CAN distinguish between various methods used in analyzing DNA evidence

Scientists isolate DNA for a variety of reasons. List these reasons

Why DNA Extraction is considered the most important step in DNA Analysis

Because it is the first step in DNA analysis

Because it needs to be purified from proteins and cell organelles

Because it is very hard to be extracted

Match the steps of DNA Extraction in order

place the swap having the cheek cells in the ependrof tube

1

microcentrifuge to separate the DNA completely from the solution

2

Add concentrated salt solution to clump the cellular contaminants together

3

microcentrifuge to separate the proteins and debris

4

Place the tube in the warm water bath

5

Add isopropyl to clump the DNA fragments together the solution to

6

Add to the tube lysis solution using micropipette

7

micropipette the solution containing DNA into another clean tube

8

collect some cells from the inside part of the mouth

9

Find the instruments used in DNA extraction
