Semiconservative replication was not the only model of DNA replication proposed during the mid-1950s, however. In fact, two other prominent hypotheses were put also forth: conservative replication ...

This experiment revealed a pattern that supports the semiconservative model of DNA replication. FURTHER RESEARCH: If you continued this experiment for two more generations (as Meselson and Stahl ...

empirically derived model of replication fork formation and unwinding, bridging gaps left by previous static or incomplete structural analyses. The study found that LTag helicase unwinds DNA ...

But Franklin wasn't just a supporting character in the DNA saga. She was the scaffolding. The discovery of the double helix model of DNA is among the most significant scientific achievements of the ...

While scientists have long known the importance of helicase in DNA replication, "they did not know how DNA, helicases and ATP work together in a coordinated cycle to drive DNA unwinding," De ...

This new study provides definitive evidence about how these secondary DNA structures can pose physical barriers to DNA ...

Chromosomes are the carriers of the genetic and epigenetic information and faithful chromosome replication is of fundamental importance for genome maintenance during normal cell proliferation. We ...

Saccharin destabilizes bacterial membranes and interferes with DNA replication, causing lysis and impairing virulence traits. The sweetener also re-sensitizes multidrug-resistant pathogens to ...
