Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists ...

A central question in molecular biology is how cells protect their chromosomes from damage during repeated cell division. At ...

Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or “ribozyme,” that carries out a fundamental reaction required to make new ...

A new method has enabled the natural structure of particularly large and complex enzymes to be revealed. Scientists have investigated a multi-enzyme complex that plays an essential role in metabolism ...

While most enzymatic activity is conducted through chemical binding interactions between molecules, in some cases, the mere presence of an enzyme can affect intracellular functions. While exploring ...

Gene editing is one of the latest breakthroughs in biology. The widely known CRISPR-Cas gene editing system provided prokaryotes (organisms that lack cell nuclei) an immunity against foreign DNA.

Researchers have made a significant advance toward the goal of using bacteria—rather than fossil fuels—to produce ethylene, a key chemical in the production of many plastics. Subscribe to our ...

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

Researchers from Tokyo Metropolitan University have developed a new structure determination method using Nuclear Magnetic Resonance (NMR) spectroscopy which shows how different parts of complex ...

Malathy Palayam, Aleczander Young, Lior Tal, and Nitzan Shabek at the UC Davis Department of Plant Biology are exploring the mechanism by which the plant hormone strigoractone regulates a massive ...
