Experiment Two

In this experiment I compared the DNA extracted from unstrained and strained kiwi. The temperature of alcohol was -15C.

DNA source: Kiwi

Observations

(immediate)

Observations

(24 hours later)

Strained DNA formed ice-like just above the surface of the alcohol. DNA formed immediately. DNA has formed a medium  cylinder-shaped at the very top of the test tube.
Unstrained (The unstrained version of the kiwi included many seeds and pulp since it was not strained). Not much DNA was produced except for very tiny particles at the very top of the test tube.

  

DNA has formed small cylinder like blobs around the middle of the test tube.
 

After the last written observations were made, DNA sources in both test tubes were carefully removed and weighed.
