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 ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

Scientists have sequenced RNA from a nearly 40,000-year-old woolly mammoth leg, the oldest ancient RNA ever recovered. These ...

Cedars-Sinai scientists have created a new experimental drug called TY1 that helps the body repair damaged DNA and restore ...

DNA and RNA methylation, initially thought to operate as distinct pathways, have been shown to interact closely, shifting our understanding of gene regulation. A team of researchers from the ...

Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing ...

Cedars-Sinai scientists have developed an experimental drug that repairs DNA and serves as a prototype for a new class of medications that fix tissue damage caused by heart attack, inflammatory ...

Many writers grouse when an editor makes a change in a story, but the consequences of changing a single word usually aren’t that dire. Not so with genetic instructions for making proteins. Even a ...
