How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde ...

Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic acid or DNA. Encoded within this DNA are the directions ...

This week at AAAS, PNNL scientists and colleagues discuss phenomics, exposomics, and the factors that influence DNA ...

This study uncovers "guided search" mechanisms, where the 3D architecture of DNA and chromatin—which packages and organizes genetic material—acts as a signpost to direct TFs to the correct genes.

depositing the DNA package inside. They made these microneedles, which are half a millimeter long, into patches and checked out how effective they were in mice and monkeys. The needles can be ...

A team of researchers has developed a novel method to enhance the precision of cancer treatment using gold nanoparticles tagged with DNA barcodes.
