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 ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

HOUSTON - (Oct. 31, 2017) - The DNA in a human cell is 2 yards long and wraps around millions of bead-like histone proteins to fit inside the cell's nucleus. Researchers at Rice University and Baylor ...

A new study based on electron microscopy techniques at low temperatures demonstrates that, during mitosis, chromosome DNA is packed in stacked layers of chromatin. The research, published in EMBO ...

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 ...

One of the challenges of working with ancient DNA samples is that damage accumulates over time, breaking up the structure of the double helix into ever smaller fragments. In the samples we've worked ...

Research shows synthetic chromosomes can be transferred to human cells with potential to improve viral resistance ...
