the Cas9 protein hooks up with the guide RNA and then moves along the strands of DNA until it finds and binds to a 20-DNA-letter long sequence that matches part of the guide RNA sequence.

Scientists have created a mega-database revealing how half a million different DNA mutations generate errors in proteins in humans. The researchers hope that the database will be used to develop ...

Scientists at Scripps Research have now captured the first detailed images of the DNA repair protein, Pol-theta, in action, revealing the molecular processes responsible for a range of cancers.

in this case histone 4 (H4), one of the nucleosome core forming histones. After purifying the chromatin fragments from the formaldehyde-fixed cells, the team immunoprecipitated the DNA-protein ...

In its structure, DNA contains a pattern for producing amino acids, proteins, lipids, sugars, and every other biomolecule an organism makes. The parts of a DNA molecule that have these ...
