Extracting Onion DNA - Science Buddies

When people think of DNA they usually visualize the elegant “twisted ladder” shape seen in everything from advertising logos to Biology textbooks. This visual is actually a kind of artist’s conception. It is a kind of scientific model, useful in helping us understand how DNA functions, but in reality impossible to see.

This acetaldehyde-modified histone H1 showed impaired DNA binding activity.

How it works:
The shampoo breaks up the membranes of the cell, allowing the DNA to come out of the cell. Filtering the fruit “goo” gets rid of the debris you don’t need. The salt can dissolve in water, but not in alcohol. In the fruit “goo”, the salt binds to the DNA and when put into the alcohol the salt solidifies and can be seen with the DNA. The salt falls to the bottom of the test tube, leaving only the DNA. The alcohol is kept cold because it helps protect the DNA.

Ristow & Obe (1978) observed enhanced reannealing of heat denatured, isolated, calf thymus DNA following incubation with acetaldehyde.

Journal of Cellular Biochemistry, August 2017
The effect of curcumin on inhibiting cancer has been recognized, but the mechanism remains elusive. This study tests a hypothesis that administration of curcumin down regulates Tregs in lung cancer (LC) patients. In this study, a group of LC patients was treated with curcumin. The peripheral Tregs and T helper (Th) 1 cells were analyzed by flow cytometry. The mechanism by which curcumin regulated the Tregs was observed by cell culture approaches. The results showed that the frequency of peripheral Treg was markedly higher in LC patients than that in healthy subjects, which was suppressed after treating with curcumin for 2 weeks. The peripheral Th1 cells were increased in LC patients after the curcumin therapy. The data of the in vitro experiments showed that curcumin converted the LC patient-isolated Tregs to Th1 cells via repressing the gene transcription of forkhead protein-3 and increasing the expression of interferon-γ. In conclusion, curcumin can convert LC patient-isolated Tregs to Th1 cells. The results suggest that curcumin may improve the antitumor immunity by regulating the tumor specific immune tolerance.

Biochemistry Project: Use basic DNA extraction techniques to extract DNA from an onion.

Just like us, banana plants have genes and DNA in their cells, and just like us, their DNA determines their traits. Using only our eyes, we couldn't see a single cell or the DNA inside of it. If we remove DNA from millions of cells, however, we will be able to view it without a microscope. That is what we will do today!

DNA is the blueprint for life. This simple experiment will show you how to extract DNA from fruit like a banana or strawberry. All you need are some fruit and some things you probably have around the house right now.
