Who is Frederick Sanger?
Who is Frederick Sanger?
Frederick Sanger, a British biochemist, was a pioneer in determining the sequence of biological molecules. His groundbreaking work on proteins and DNA revolutionized molecular biology.
What is insulin?
What is insulin?
Insulin is a protein hormone that helps regulate blood sugar levels. Sanger's precise determination of its amino acid sequence changed how proteins were understood.
What is Sanger sequencing?
What is Sanger sequencing?
Sanger's dideoxy method is a technique for sequencing DNA. It works by creating DNA fragments of varying lengths, which are then analyzed to determine the order of nucleotides.
