Why is agarose gel electrophoresis done after DNA isolation?

Answer and explanation

Correct answer: To check the presence and integrity of DNA

In agarose gel electrophoresis, DNA migrates through the gel according to its size and becomes visible as bands. A clear, expected band indicates the presence of intact, good-quality DNA, whereas a smear may indicate fragmented or degraded DNA. Spectrophotometry or fluorometry is more suitable for measuring the exact DNA quantity. Exam tip: associate a clear gel band with generally good DNA integrity.
