How nitrate regulates gene expression in legumes

Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful (Figure 1), but precisely how nitrate presence controls nodule formation ...

The birth of a bacterial tRNA gene

Translation is the process by which genetic information is converted into proteins, the workhorses of the cell. Small molecules called transfer RNAs (tRNAs) play a crucial role in translation; they are the adapter molecules ...

Evolutionary conflicts predicted

Evolution seems to be an unpredictable process. However, predicting the constraints of evolution is possible. Researchers from AMOLF and the French ESPCI have demonstrated this using their mathematical method, followed by ...

How to keep the nucleus clean

Cells are small factories that constantly produce protein and RNA molecules by decoding the genetic information stored in the DNA of their chromosomes. The first phase of this decoding, the transcription process, 'transcribes' ...

New DNA amplification capsule holds promise for fighting diseases

DNA amplification—a molecular "photocopying" technique where genetic material is replicated—has many applications in scientific research, forensic science, and medical laboratories. It is useful for detecting and identifying ...
