DNA replication basics. The DNA double helix is made from two strands that run in opposite directions. Each strand is made of a series of bases, A, T, C and G, that pair up between the strands: A to T ...

Almost all life on Earth is based on DNA being copied, or replicated. Now for the first time, scientists have been able to watch the replication of a single DNA molecule, with some surprising ...

Nature - DNA replication and recombination. Skip to main content. ... Focusing on the schematic illustration in a, two DNA polymerase molecules are active at the fork at any one time.

DNA Polymerase enzyme syntheses labeled educational vector illustration. Image Credit: VectorMine / Shutterstock. Every time a cell divides, DNA polymerase is required to help duplicate the cell ...

This study reveals how SV40 helicase unwinds DNA, highlighting ATP hydrolysis's role in translocation and offering insights ...

The first step in DNA replication requires the assembly of a group of proteins called the Origin Recognition Complex (ORC). Researchers have determined how the ORC assembles during the cell ...

A study links the loss of DNA methylation across the genome—as is common in cancer—to the disruption of the 3-D compartments that organize the genome and to the timing of DNA replication. Cell lines ...

A new study from King Abdullah University of Science and Technology (KAUST), published in Nature, captures the moment DNA begins to unwind, allowing for all the events that follow in DNA replication.

But if the proton does not make it back by the time the two DNA strands separate—the first step of DNA replication—the cytosine might bind to a different base, adenine, rather than guanine ...
