Which molecular technique is used to separate DNA fragments by size?

Step 1: Understand that DNA is made up of small pieces called fragments.
Step 2: Know that these fragments can be of different sizes.
Step 3: Learn that gel electrophoresis is a technique used to separate these DNA fragments.
Step 4: In gel electrophoresis, a gel is made, and the DNA fragments are placed in it.
Step 5: An electric current is applied to the gel, causing the DNA fragments to move.
Step 6: Smaller DNA fragments move faster and travel further in the gel than larger ones.
Step 7: After the process, you can see the separated DNA fragments, which helps in analysis and comparison.
