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 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 ...

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 ...

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 ...
