In a study published in Nature, researchers report the successful in vitro reconstitution of meiotic DNA double-strand breaks ...

Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

A double-strand DNA break (DSB) occurs or arises when both strands of the DNA duplex are severed, often as the result of ionizing radiation. They are particularly deleterious as the DNA ends can ...

This would create long regions of vulnerable ssDNA ... although the latter can be stabilized and protected by single-strand DNA binding proteins. Researchers have recently discovered that ...

Using an approach called DNA origami, scientists at Caltech have developed a technique that could lead to cheaper, reusable ...

A coarse-grained model of the DNA origami lilypad used in the study. The tails hanging down indicate where redox reporters are located. For scale, the diameter of the disk is approximately 80 nm.

Researchers have revealed new details about the CRISPR-Cas5-HNH/Cascade complex, a variant of the type I-E CRISPR-Cas system, ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...
