Explicación
## Step 1Gel electrophoresis is a technique used to separate DNA molecules based on their size. The DNA molecules are placed in a gel and an electric current is applied. ## Step 2DNA molecules are negatively charged due to the phosphate groups in their backbone. This negative charge is due to the presence of phosphate groups in the DNA backbone.## Step 3When an electric current is applied, the negatively charged DNA molecules will be attracted to the positive electrode. This is because opposite charges attract each other.## Step 4Therefore, in gel electrophoresis, DNA travels towards the positive electrode because it has a negative charge.
