(Phys.org)—A team of researchers affiliated with several institutions in South Korea has found a way to introduce an enzyme into a cell using the CRISPR technique without having to use a bacterial carrier—the result, ...
A study done by Ludwig-Maximilians-Universitaet (LMU) in Munich physicists demonstrates that fundamental characteristics of mopolymeric lecules, such as their subunit composition, are sufficient to trigger selection processes ...
