DNA replication is one of the most basic processes ... Meanwhile, as the helicase separates the strands, another enzyme called primase briefly attaches to each strand and assembles a foundation ...

Without a connecting link, the CMG complex could just "run off" and leave pol-a/primase behind. This would create long regions of vulnerable ssDNA. Therefore, the second rule in DNA replication is ...

Scientists have provided the most detailed account yet of the earliest stages of DNA replication, an essential process for ...

Researchers at the Center for Embryology and Healthy Development (CRESCO) aim to find out why so many early embryos fail in ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life.

During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these ...

Scientists have captured the first detailed 'molecular movie' showing DNA being unzipped at the atomic level -- revealing how cells begin the crucial process of copying their genetic material.
