The base-pair sequence is usually referred to as the primary structure of DNA. This sequence determines the actual structure of the DNA. DNA carries the genetic code and this is what is read by ...

Ever since Francis Crick and James Watson determined the primary structure of DNA to be a double helix, scientists have wondered how DNA is further organized to allow its entire length to pack ...

The question therefore arises of how chromatin structure, in which DNA is normally highly compacted ... the root-mean-square deviations for the primary bound-phosphate group (1.27 and 1.39 ...

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 ...

Scientists have developed a new method of imaging the building blocks of life. It involves an electron microscope and a bed of nails. DNA, we are taught early on, is colorful. The building block ...

The discovery of DNA’s double helix structure -- considered one of the towering achievements of the 20th century and perhaps all of scientific history -- is key to understanding the primary ...
