THE reaction of a solution of DNA with an alkylating agent such as dimethyl sulphate results in the production of acid as the alkylating agent is hydrolysed by water. To maintain the solution at 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 ...

One such mechanism is base excision repair (BER), where the mutated adenine is recognized and removed by DNA glycosylases, followed by the synthesis of the correct base pair. Adenine can exist in ...

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 ...

Their approach, developed for ancient fragments of DNA from Neanderthals, was more sensitive than earlier methods. When they analyzed Hauser’s mitochondrial DNA, or mtDNA — genetic code ...

Produced by ElevenLabs and News Over Audio (NOA) using AI narration. DNA might contain health information, but unlike a doctor’s office, 23andMe is not bound by the health-privacy law HIPAA.

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.

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, ...

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.

Finding a naturally occurring DNA-protein hybrid and determining how a bacterium can be induced to make it would streamline what is now a slow, labor-intensive process, Nair said. "Lots of high ...
