For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

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

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 ...

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 ...

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 ...

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.
