New research shows genome duplication in the ancestor of modern gymnosperms, a group of seed plants that includes cypresses and pines, might have directly contributed to the origin of the group over ...

Replication fork stalling can provoke fork reversal to form a four-way DNA junction. This remodelling of the replication fork can facilitate repair, aid bypass of DNA lesions, and enable replication ...

Noninvasive prenatal testing (NIPT), which relies on cell-free fetal DNA in the mother's blood, is increasingly common. Yet two studies published online Apri 1 in the New England Journal of Medicine ...

Gene duplication is the primary mechanism by which new genes emerge. Models and empirical studies have shown that paralogous genes are maintained because of dosage benefits, the partitioning of ...

A team at Washington University traced how plants gained duplicate DNA-control enzymes that evolved into new functions, boosting their ability to handle stress. The finding shows how a single genetic ...

A new study led by the Roslin Institute seeks to unlock the mysteries behind a powerful genetic phenomenon that has played a ...

Cold Spring Harbor, N.Y. – Before a cell can divide into two, first it must duplicate its genetic material--the DNA packed in its chromosomes. The two new sets of chromosomes then have to be separated ...

The genome of the evolutionary ancestor of humans and present-day apes underwent a burst of activity in duplicating segments of DNA, according to a study to be published in Nature Feb 12, the 200th ...

Researchers at USC have developed a yeast model to study a gene mutation that disrupts the duplication of DNA, causing massive damage to a cell's chromosomes, while somehow allowing the cell to ...
