Scientists at the University of Copenhagen, led by the Spanish Professor Guillermo Montoya, are investigating the molecular features of different molecular scissors of the CRISPR-Cas system to shed light on the so-called ‘Swiss-army knives’ of genome editing. Montoya’s research group has visualized the atomic structures of the Cpf1 and Cas9 proteins to analyse each of their properties and peculiarities that make them ideal for different applications in gene modification.
Researchers from the University of Copenhagen (Denmark), led by the Spanish researcher Guillermo Montoya, have discovered how Cpf1, a new molecular scissors unzip and cleave DNA. This member of the CRISPR-Cas family displays a high accuracy, capable of acting like a GPS in order to identify its destination within the intricate map of the genome. The high precision of Cpf1 will improve the use of this type of technology in repairing genetic damage and in other medical and biotechnological applications.
The cave bear who once inhabited the Iberian peninsula up until 24,000 years ago used to return to the cave in which it was born to hibernate and raise its young. This habit played an important role in its extinction and furthermore explains why only one genetic lineage can be detected in each of the caves where remains have been found.
