Was the DNA OK?

On day 5 we used a machine to find out the how much DNA was in each sample of DNA we got the previous day. Using the results from the machine we then found out how much of each sample we needed for the next thing we did.

The next thing we did was run a gel. This was done to see if from the process of removing the DNA from the previous day had in anyway broken it up. That was made from a block of a gel called agarose gel with agarose powder and also a dye which would cause it to show up under UV light. A small amount of each DNA sample mixed with a dye were put in little wells on the gel and and on two of the wells only dye was put in. The gel was then submerged in a liquid called a buffer and electricity was put through it. The wells with just dye moved across the gel creating a sort of ruler which measured how broken up the DNA was so depending on how far the DNA samples moved across the gel showed how broken up the DNA was. We would then put the gel under UV the next day to be able to see how all the substances had moved along it better.
