Our cells' identity is shaped by DNA tags called methylation. New tech, scDEEP-mC, maps these tags in single cells with ...

Franklin W. Stahl, an American molecular biologist whose landmark 1957-58 experiment with colleague Matthew Meselson revealed ...

He and a colleague proved a theory advanced by the Nobel Prize winners James Watson and Francis Crick, who discovered DNA’s ...

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

Whether antiretroviral therapy (ART) is always completely suppressive, or HIV might continue to replicate at low levels despite ART in some people with HIV (PWH), is still debated. Here, we ...

Earth was an “RNA World,” meaning that life must’ve first replicated from RNA before the arrival of proteins and DNA. Unfortunately, scientists have failed to find evidence of this “first replicator” ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

The reliability of the DNA replication process depends on genome stability, which is maintained by DNA repair mechanisms that correct any mistakes that occur during DNA replication.

DNA replication is a process that occurs when DNA in the cells copies itself. This helps ensure that each new cell has its own complete genome during cell division.
