“In the early days, you couldn’t do much with DNA because it was a very large molecule,” Roberts recalled. “As soon as the Type II restriction enzymes were discovered—and HindII in particular—it was ...

When nucleic acids like DNA or RNA build up in a cell's cytoplasm, it sets off an alarm call for the immune system. Enzymes usually clear these nucleic acids before they cause an issue ...

The discovery of restriction enzymes began with a hypothesis. In the 1960s, Werner Arber observed a dramatic change in the bacteriophage DNA after it invaded these resistant strains of bacteria ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

To amplify a DNA fragment, scientists need to expose it to a series of thermal cycles: first the fragment is heated, causing it to open up, then the temperature is lowered so that an enzyme can ...

Zhijian “James” Chen, a biochemist at the University of Texas Southwestern Medical Center, was awarded the 2024 Albert Lasker Basic Medical Research Award for the discovery of the cGAS enzyme that ...

Scientists at the University of Leicester have captured the first detailed “molecular movie” showing DNA being unzipped at ...

University at Albany researchers at the RNA Institute are pioneering new methods for designing and assembling DNA ...
