The Central Board of Secondary Education schedules Class 10 and 12 exams from February 17, 2026, highlighting key questions and topics.
O trabalho tem como objetivo analisar as associações de variantes polimórficas dos genes PRL e BLG com resistência e suscetibilidade à mastite em vacas holandesas. O estudo experimental consistiu na ...
A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act like molecular anchors. The work confirms these tags actively silence genes, ...
Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...
ABSTRACT: The aim of this work was to study the competition between Helicobacter pylori isolates susceptible to clarithromycin and their resistant mutants, in terms of growth, by co-culture over an ...
“The laws of inheritance are quite unknown,” Charles Darwin acknowledged in 1859. The discovery of DNA’s shape altered how we conceived of life itself. The X-ray crystallography by Rosalind Franklin ...
James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died, according to ...
ABSTRACT: Background: Hepatitis B virus (HBV) infection remains a significant public health concern in developing countries. HBV genotypes influence viral evolution and genetic diversity. This study ...
Is it the invasion of the genome snatchers? Just in case the idea of aliens walking around in human skin suits wasn’t frightening enough. An outlandish study asserts that aliens might have abducted us ...
A groundbreaking study has revealed that your mom and dad’s DNA don’t just pass on telomere length, they actively reshape it in the first days of life, influencing how we age and our risk of ...
The world's oldest DNA comes from a 2.4 million-year-old ecosystem in Greenland. Will scientists eventually sequence even older DNA? When you purchase through links on our site, we may earn an ...
