How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals ...

With the long-term goal of creating living cells from non-living components, scientists in the field of synthetic biology ...

Researchers have now shown that transcription factors can bind to RNA as well, and that attachment has significant impacts on gene expression. The findings have been reported in Molecular Cell . When ...

A ll cells in the body reach a point where they stop dividing, but some get there quicker under the influence of pressures, such as DNA damage or oxidative stress. 1 Biologists have long studied how ...

Once dismissed as “junk,” a group of RNA molecules has been found to help regrow damaged nerves in mice in new research. The ...

Every living cell must interpret its genetic code - a sequence of chemical letters that governs countless cellular functions.

These non-coding transcripts can mediate gene expression and the activity of mRNAs after transcription. RNA polymerase III RNA polymerase III 2 transcribes rRNA genes into small RNAs like transfer RNA ...

S enescent cells, those that persist in the body despite having halted cell division, undergo a process called cryptic transcription, whereby they produce RNA transcripts from short sequences nested ...

Not all RNA molecules are used to generate protein, for example. It's long been thought that enzymes called DNA polymerases only function to copy the genome or make repairs to DNA. But now, scientists ...

With the long-term goal of creating living cells from non-living components, scientists in the field of synthetic biology work with RNA origami. This tool uses the multifunctionality of the ...

A bacterial protein helps to stop transcription -- the process of making RNA copies of DNA to carry out the functions of the cell -- by causing the cellular machinery that transcribes the DNA to ...

Every living cell must interpret its genetic code—a sequence of chemical letters that governs countless cellular functions. A ...
