Front

What happens to DNA fragments during gel electrophoresis?

Back

They are separated based on size, with smaller fragments moving further than larger ones.

Front

What is the purpose of using a DNA ladder in gel electrophoresis?

Back

A DNA ladder is used as a reference to determine the size of DNA fragments.

Front

What does it indicate if both elephants are heterozygous for a gene?
