An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have ...

Chromatin facilitates the combining of DNA and proteins to form chromosomes, and the rest is history. Scientists are still baffled by the condensing of DNA, which Vera Pancaldi, one of the study ...

Among the many marvels of life is the cell’s ability to divide and thus enable organisms to grow and renew themselves.

Chromatin -- the intertwined histone proteins and DNA that make up chromosomes -- constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle ...

Supercoiling as the motor of chromatin loop extrusion. Andrzej Stasiak's DNA and Chromosome Modelling Group at SIB set out to understand the nature of the motor that is pushing cohesin along the ...

Chromatin assembly is required for the duplication of eukaryotic chromosomes and functions at the interface between cell-cycle progression and gene expression. The central machinery that mediates ...

EDINBURGH, Scotland, Nov. 21 (UPI) --Only half of each chromosome is made up of DNA material. An unexplained sheath accounts for most of the rest of the material inside a chromosome. Until now ...

After treating the chromosomes with low concentrations of enzymes that cut DNA at specific points, they discovered there was no support left, and the chromosomes dissolved.

To do that, cells divide and replicate their DNA, which is wrapped into labyrinthine libraries inside chromatin, the stuff inside chromosomes. Extended in a straight line, DNA in a single cell can ...

However, the factors that control the shape of chromosomes—the dimensions and degree of DNA condensation—remain enigmatic. Kakui was intrigued by how genomic DNA is stored within cells.
