Sequencing without PCR reduces bias in measuring biodiversity

DNA barcode sequencing without the amplification of DNA by PCR beats the problem of false positives which can inflate estimates of biodiversity, finds a study published in BioMed Central and BGI Shenzhen's open access journal ...

Spinal tap: Using cactus spines to isolate DNA

Isolation of DNA from some organisms is a routine procedure. For example, you can buy a kit at your local pharmacy or grocery store that allows you to swab the inside of your cheek and send the sample for DNA sequencing. ...

Improving DNA amplification from problematic plants

The polymerase chain reaction (PCR) is a common technique used to amplify, or copy, pieces of DNA. Amplified DNA is then used in genetic analyses for everything from medicine to forensics. In plant research, PCR is a vital ...

NEC plans DNA analyzer for nearly-instant results

(Phys.org)—NEC is working on a DNA analyzer that is the size of a suitcase, portable enough to be taken to crime scenes. The NEC analyzer integrates all steps required in DNA analysis. By 2014, NEC intends to issue a model ...

Bioluminescent technology for easy tracking of GMO

It is important to be able to monitor genetically modified (GM) crops, not only in the field but also during the food processing chain. New research published in BioMed Central's open access journal BMC Biotechnology shows ...

DNA from old insects -- no need to destroy the specimen

In a new study published April 1 in the online, open-access, peer-reviewed journal PLoS ONE, ancient DNA (aDNA) is retrieved from various insect remains without destruction of the specimens.
