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

In both cases, replication occurs so quickly because multiple polymerases can synthesize two new strands at the same time by using each unwound strand from the original DNA double helix as a template.

Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

According to the conservative replication model, the entire original DNA double helix ... would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA.

Traditional methods for detection of DNA methylation require steps that can damage DNA. Novel methods can directly detect intact DNA methylation from the original DNA strand, without damage, and ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer.

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note - RNA ...

In a study published in Nature, researchers report the successful in vitro reconstitution of meiotic DNA double-strand breaks (DSBs) formation. Meiosis, a specialized form of cell division in most ...

(In the 2006 paper, Rothemund famously used the technique to create miniature DNA smiley faces measuring 100 nanometers across and 2 nanometers thick). Researchers begin with a long strand of DNA ...
