How do you read gel electrophoresis results?

Answer 1

there are different gel electrophoresis for DNA and proteins by gel electrophoresis we resolve proteins and DNA according to different sizes

Nowadays, a more sophisticated method called gel doc is used, which can be connected to computers and allows images to be taken. In the case of SDS PAGE (proteins), we use staining and destaining dye to read the results. In the case of agarose gel (DNA), UV light is used, which is absorbed by EtBr and gives orange color.

To read gel electrophoresis results, first identify the DNA bands on the gel. Each band represents DNA fragments of different sizes. The smaller fragments travel farther through the gel, so they will appear closer to the bottom of the gel. Compare the bands to a molecular weight marker to estimate the sizes of the DNA fragments. The intensity of the bands corresponds to the amount of DNA present in each fragment.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
