New methods such as genomic sequencing and mass spectrometry have prompted dramatic increases in the amount of molecular data available to scientists and health care professionals seeking more refined ...

Long known as a messenger within cells, RNA is increasingly seen as life’s molecular communication system — even between organisms widely separated by evolution. For a molecule of RNA, the world is a ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...

Inside the cell reside many tiny assembly factories and warehouses that gather together all of the proteins and RNAs-which ...

In the form of DNA, nature shows how data can be stored in a space-saving and long-term manner. Bioinformatics specialists are developing DNA chips for computer technology. Researchers show how a ...

Researchers at Stockholm University carefully ground up bits of muscle and other tissue from Yuka and nine other woolly mammoths, then used special chemical treatments to pull out any remaining RNA ...

Scientists discovered that the first 100 base pairs of human genes are unusually prone to mutations, especially during the ...
