Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

Retrotransposons are sequences of DNA in animal genomes that can replicate and reinsert themselves back into the genome. Experiments in flies and other model systems reveal that retrotransposons ...

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 ...

In a complex called chromatin, long strands of DNA in cells' nuclei are tightly wrapped around a scaffolding of proteins, like a rolled-up ball of yarn. A new study by Weill Cornell Medicine ...

To our immune system, a potentially lifesaving gene therapy can look a lot like a dangerous infection. That's because most genetic medicine uses viruses or double-stranded DNA to deliver genetic ...

Circular DNA, thought to be an accidental byproduct, is borrowing the cell’s DNA repair mechanisms to copy itself DURHAM, N.C. -- Like its viral cousins, a somewhat parasitic DNA sequence called a ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study ...
