Medicine & TechnologyResearchers at the University of California - Riverdale devised a "chemical nose" that could sniff out changes in the DNA structure, such as folds in the DNA sequence, to prevent diseases.
DNA can sometimes form a four quadruple-helix rather than the usual double helix. Scientists are looking into this rare quadruple-helix to find its connection to diseases, such as cancer.
Scientists found four-stranded DNA structures, called G-quadruplexes in cancer cells that can serve as the weak spots of the cell that could help scientists develop treatment methods for cancer.
