WE have formulated a structure for the nucleic acids which is compatible with the main features of the X-ray diagram and with the general principles of molecular structure, and which accounts ...

not nucleic acid, but by the late 1940s, DNA was largely accepted as the genetic molecule. Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked.

The resulting RNA molecule, typically mRNA, carries the genetic message from the nucleus to the cytoplasm for protein synthesis. Nucleic acids are the foundation of genetic engineering techniques, ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA ... that DNA, a nucleic acid, carries genetic information. But no one knew how ...

Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic acid or DNA. Encoded within this DNA are the directions ...

Deoxyribonucleic acid (DNA) is the information-carrying molecule found in all living organisms. In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like ...
