For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation ...

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

Scientists have captured the first detailed 'molecular movie' showing DNA being unzipped at the atomic level -- revealing how cells begin the crucial process of copying their genetic material.

DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands, allowing each strand to be ... From a medical perspective, many viruses ...

On their own, however, polymerases aren't good at staying on the DNA strand. They require CTF18-RFC in humans and Ctf18-RFC in yeast to thread a ring-shaped clamp onto the DNA leading strand ...

"It may be necessary to reconsider or evaluate the effects of single-strand ... Chan Medical School. More information: Kazuhisa Uchida et al, Encapsulation of a Single-Stranded Form of DNA ...

In addition to Lander and Zerio, authors of the study, "Human polymerase θ helicase positions DNA microhomologies for double-strand break repair," include Yonghong Bai, Brian A. Sosa-Alvarado and ...

Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a ...

Once transcription is initiated, the DNA double helix unwinds and RNA polymerase reads the template strand, adding nucleotides to the 3′ end of the growing chain (Figure 2b). At a temperature of ...

DNA replication is the process by which the DNA molecule makes an exact copy of itself during cell division. The double helix unwinds, and each strand serves as a template for the synthesis of a new ...
