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. A new study from King ...

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

Arthur Kornberg compared DNA to a tape recording of instructions ... Nonetheless, scientists are familiar with the basic steps in the replication process, and they continue to rely on this ...

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

the DNA replication checkpoint is the master surveillance system that steps in when a cell has problems during DNA replication. What does the DNA replication checkpoint really monitor? This ...

The DNA repair and replication pathways converge on a common final step in which the continuity of the repaired DNA strand is restored by DNA ligase, an enzyme that converts nicks into phosphodiester ...

So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein.

A team led by Professor Kazuhiro Maeshima of the National Institute of Genetics (ROIS) and SOKENDAI in Japan has developed a ...

They then pull the two strands apart, allowing other enzymes to complete the replication. Without this first step, no DNA can be replicated. In this way, helicases are machines or, because of ...
