在血液透析中，透析液质量关乎患者健康，细菌 dna（bdna）片段会引发炎症反应。研究人员评估了内毒素截留滤器（etrf）清除 bdna 的能力及消毒剂灭活 bdna 的效果，发现次氯酸钠消毒效果佳，为提升透析液质量提供依据。

Beyond revealing a secret to bacterial survival, the research has uncovered components that could be applied to gene editing: guide DNA, which is more stable and cheaper to synthesize than guide ...

Bacterial genomes tend to have very few transposons—the extra DNA isn't really in keeping with the bacterial reproduction approach of "copy all the DNA as quickly as possible when there's food ...

Researchers have identified buried copper ore by testing the DNA of microbes in the surface soil. These ‘biological ...

Bacterial telomeres. While most bacterial DNA is in the form of plasmids, there are some that have linear DNA that contain telomeres. Though the presence of telomeres at the ends of the linear ...

IS110 produces a recombinase protein and expresses a noncoding RNA. The team found that the noncoding RNA contained two loops, a donor loop that could recognize IS110’s own DNA, and a target ...

New DNA Test Delivers Results in 2 Days Health Minister Ashley Dalton praised the collaboration. “This groundbreaking use of the technology in hospitals will cut diagnosis times down from weeks ...

In a study reported in the online edition of Science on Aug. 10, 2023, a group of synthetic biologists from the University of California (UC) San Diego and clinicians from Australia have engineered ...

Researchers have uncovered the oldest known cases of the plague in Great Britain. Experts share what the 4,000-year-old DNA says about the history of the disease.

The BREX system enhances bacterial antiviral defense by modifying its own DNA to distinguish it from viral DNA, a mechanism more complex than classical restriction-modification systems.
