Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...

Thus, lactose, from which allolactose is formed ... For example, specific sequences in DNA serve as binding sites for specific proteins that modulate the binding of RNA polymerase, the enzyme ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Earlier that morning, in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic acid, or DNA. This discovery changed the world of science and medicine ...

All modern humans have some Neanderthal DNA in them, which can have a variety of impacts on our genetic makeup. Lactase persistence (aka, lactose tolerance) was once thought to have evolved in ...
