What do a human, a rose, and a bacterium have in common? Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic ...

There's a lot of DNA within the nucleus -- about six feet if you could unravel it and stretch it out end to end. To fit such a long molecule within the tiny space of the nucleus, DNA bends and ...

DNA sequencing is a laboratory method used to determine the sequence of a DNA molecule. The method was developed by Frederick Sanger in 1975, who was later awarded the Nobel Prize in chemistry in ...

These bases are the rungs of the DNA ladder. (It takes two bases to form a rung -- one for each side of the ladder.) A sugar molecule, a base, and a phosphate molecule group together to make up a ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

Francis Crick and James Watson with a model of the DNA molecule At midday on 28 February 1953, Francis Crick and James Watson walked into The Eagle pub in Cambridge and announced “We have ...

DNA is the molecule that holds the instructions for all living things. DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Replication of ...

In 1952, Alfred Hershey of Cold Spring Harbor Laboratory and his lab technician, Martha Chase, wanted to confirm that DNA was the carrier of genetic information. They tagged the protein coating of ...

Both the lilypad and the electrode have short DNA strands available to bind with an analyte, a molecule of interest in solution -- whether that be a molecule of DNA, a protein, or an antibody.
