American researchers have successfully completed the full sequencing of a human chromosome for the first time. This ...

DNA is one of the most intensely studied molecules, and scientists continue to uncover new layers of structural complexity. Now researchers have found direct evidence from NMR experiments that DNA ...

How can just four nitrogenous bases--adenine, cytosine, guanine, and uracil--possibly code for all 20 amino acids? Thus, early researchers quickly determined that the smallest combination of As, Cs, ...

Researchers at The Scripps Research Institute (TSRI) claim to have created the first stable semisynthetic organism with extra bases added to its genetic code. The single-celled organism is also able ...
