Genetics and genomics news covering DNA sequencing, gene editing, CRISPR, hereditary disease research, and population genomics.
University of Sheffield researchers have published the first direct visual evidence of how separate DNA molecules align in a 'groove-to-groove' arrangement. Using atomic force microscopy, they confirmed that positively charged ions act as molecular bridges, validating the long-theorized 'DNA zipper' model of genetic sequence recognition.
Research published in JAMA Network Open indicates children of centenarians face significantly lower risks of death, heart disease, and hypertension. Even after adjusting for lifestyle factors, data suggests genetic advantages contribute to these health outcomes.
The article explains how advances in DNA research are transforming prostate cancer diagnosis beyond standard PSA tests. It details the use of cell-free DNA in blood plasma to correlate genetic material with treatment efficacy and disease response, offering a more precise diagnostic tool for patients.
