The bacteria that cause tuberculosis (TB) may have an "on-off switch" that lets them pause and restart growth, according to a ...

To fully understand how genome integrity is maintained, David Cortez, Ph.D., and colleagues have generated a "catalog" of the proteins present at sites of DNA duplication (replication forks ...

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 ...

Failures in DNA replication can lead to cancer, birth defects or other harm Video shows single pieces of double-helix DNA being copied Single-molecule view gives new insights into this process ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind ...

As previously mentioned, the location at which a DNA strand begins to unwind into two separate single strands is known as the origin of replication. As shown in Figure 1, when the double helix ...

A new study has found that the photosynthetic bacterium Synechococcus elongatus uses a circadian clock to precisely time DNA replication ... published online on May 10 in Proceedings of the ...
