DNA-based nanotechnology employs branched motifs to these ends. This effort has been quite successful, because these unusual motifs of DNA present an extremely favorable construction medium ...

Liver biopsies were obtained from 607 patients at the Nagasaki University Hospital (Nagasaki, Japan) between January 1980 and December 1999. Of these 607 patients, 47 were diagnosed with HCC based ...

Circulating tumor DNA (ctDNA) assays are examples of what is currently called a liquid biopsy, in which a sample of peripheral blood from a cancer patient is analyzed with the aim of detecting ...

聚合酶連鎖反應（英語：Polymerase chain reaction，縮寫：PCR）又稱多聚酶链式反應，是一项利用DNA双链复制的原理，在生物体外复制特定DNA片段的核酸合成技术。透过这項技术，可在短时间内大量扩增目的基因（標的基因），而不必依賴大腸桿菌或酵母菌等生物體。DNA ...

With so many at-home DNA tests now available to consumers, learning more about your ancestry is easier than ever. Plus, these tests make for thoughtful, unique holiday gifts. All you have to do is ...

DNA (deoxyribonucleic acid) is the nucleic acid polymer that forms the genetic code for a cell or virus. Most DNA molecules consist of two polymers (double-stranded) of four nucleotides that each ...

Scientists say they have recovered the oldest known Homo sapiens DNA from human remains found in Europe, and the information is helping to reveal our species’ shared history with Neanderthals.

The researchers cataloged the segments of Neanderthal DNA in each person’s genome, then compared them to see where those segments appeared and how that changed over time and distance.

Today, all humans except those with only African heritage bear the marks of this union in their DNA. The study's findings suggest this genetic exchange took place roughly 80 generations before the ...
