DNA has genetic information that controls our cells. So, DNA is like a blueprint that shows how to construct components of cells like proteins and ribonucleic acid (RNA). This information is carried down to newer generations through inheritance. |
In order to make DNA visible. The Gel has to be soaked in a dye (ethidium bromide) to bind with the DNA and rinsed off after. Ethidium bromide helps to make DNA visible by glowing brightly in UV rays. |
