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 ...

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 ...

For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation ...

DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Replication of DNA DNA replication is the process by which a cell makes an identical ...

Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958 ...

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

A new study suggests that severe trauma, like that experienced in war, can leave epigenetic “scars” on DNA that endures for generations. In the early 1980s, the Syrian regime carried out a ...
