A cell's identity is based on the genes it expresses, and scientists have been studying gene expression mechanisms for many years. But the process involves molecules that are too small to see, until ...

The team of researchers, led by Dr Rafael Carazo Salas from the Department of Genetics, combined high-resolution 3D confocal microscopy and computer-automated analysis of the images to survey the ...

The development of an embryo is one of the most fundamental processes in biology. Early in this process, it is determined which cells will give rise to which tissues—controlled by epigenetic marks ...

All proteins in a cell are assembled by complicated molecular machines. The precursors of these ribosomes are produced in the cell nucleus and then enter the cell through the so-called nuclear pores.

Chemists reveal method for differentiating PCET mechanisms -- a key step for steering fundamental energy conversion and redox catalysis processes. Redox reactions form the basis of many fundamental ...

A research team from the University of Hong Kong (HKU) led by Professor Xiang David Li from the Department of Chemistry in collaboration with Dr Yuanliang Zhai from the HKU School of Biological ...
