Water shortens the shelf life of DNA. Biosample integrity is questionable for samples stored in a wet environment owing to the persistent risk of DNA hydrolysis, even at low temperature.

On ATP hydrolysis, which releases the DNA, a new heteroduplex is produced if strand exchange has occurred. Otherwise, the filament reforms for additional ATPase cycles of dsDNA binding, homology ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a ...

科技日报北京9月1日电 （记者张梦然）DNA因其标志性的双螺旋结构而广为人知。但澳大利亚加文医学研究所科学家发现，人类基因组还含有超过5万个不寻常的结状DNA结构，称为i-基序。最新一期《EMBO》杂志发表了这些独特DNA结构的第一张综合图谱，揭示了它们在 ...

This important work shows how a simple geophysical setting of gas flow over a narrow channel of water can create a physical environment that leads to the isothermal replication of nucleic acids. The ...

DNA is the molecule that holds the instructions for all living things. DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Replication of ...

Chemical synthesis methods include the cyclization of urea with β-aminoacrylonitrile or the hydrolysis of 2-amino-4,6-dichloropyrimidine. Cytosine can also be isolated from DNA or RNA through ...

These days, testing your DNA is easier than ever. There are many at-home DNA testing kits to choose from, so all you need are DNA samples to learn more about your heritage and family history.

Until recently, wildlife surveys would involve going out and physically looking for species such as plants, birds or mammals. But now we can also use DNA sequencing technologies to monitor wildlife, ...

In nature, this is achieved by a machinery of proteins: motor proteins powered by chemical energy from ATP hydrolysis pull together a ring of filaments of the protein actin. Adenosine triphosphate, or ...

Every human has unique DNA (except for identical twins who share the same DNA, as they both came from the same initial cell). Forensic scientists use the unique nature of DNA to help catch criminals.
