Define unit of measurement for DNA fragment size

1 answer

The size of DNA fragments is commonly measured in base pairs (bp). Other units that may be used to describe larger DNA fragments include kilobase pairs (kb), where 1 kb equals 1,000 base pairs, and megabase pairs (Mb), where 1 Mb equals 1,000,000 base pairs. These units are crucial in molecular biology for quantifying the length of DNA sequences, whether in the context of cloning, sequencing, or gel electrophoresis.
