How to read gel electrophoresis bands?
To read a gel electrophoresis band, follow these steps:

1. Examine the gel image: Before interpreting the bands, ensure that the gel image is clear, and the bands are well-separated. The bands should appear as dense, smudgy regions within the gel, and the background should be relatively clear.

2. Determine the size of the bands: Compare the bands to a molecular weight marker or ladder that is usually included
Gel electrophoresis is a common laboratory technique used to separate DNA or RNA fragments based on their size and charge. Following electrophoresis, the gel is stained to visualize the separated bands. However, interpreting the results of a gel electrophoresis experiment can be challenging, especially for those new to the technique. Here are some general guidelines for reading and interpreting gel electrophoresis bands:

1. Familiarize yourself with
