A mixture of DNA and proteins—known as "chromatin"—sits inside every cell nucleus as a jumbled puddle of genetic information. As cells prepare to divide during mitosis, the chromatin is condensed into ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

Dr. Yasuhiro Arimura studies chromatin, the mixture of DNA and DNA-packaging proteins. Chromatin is “marked” with numerous chemical or structural cues that enable cells to organize DNA and manage how ...

If I asked you, dear reader, to come up with a shortlist of the most monumental scientific achievements of the last century, chances are the Human Genome Project (HGP) would appear somewhere on that ...

AMES, Iowa – In their long strings of nucleotides, DNA molecules hold massive troves of genetic data providing instructions for how living organisms should function – the blueprint of life. How the ...

A team of scientists studying cell division developed a special light microscopy system and used it to analyze the molecular density of cellular environments. Their results provide a novel insight ...
