Life runs on instructions you never see. Every cell reads DNA, turns that message into RNA, and then builds proteins that ...

The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

Cancers begin with abnormal changes in individual cells, and the ability to track the accumulation of mutations at the single-cell level can shed new light on the early stages of the disease. Such ...

IOCB Prague researchers showed that dinucleoside polyphosphates, known as alarmones, can initiate RNA transcription and form ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double helix ...

Structural comparison of DNA and the artificial TNA, a Xeno nucleic acid with the natural base pairs AT and GC and an additional base pair (XY). The DNA carries the genetic information of all living ...

Unquestionably, we will emerge from this revolutionary period with modified views of components of cells and how they operate, but only, however, to await the emergence of the next revolutionary phase ...
