Figure 1. Experimental study design. The figure summarizes steps taken and the number of samples processed at each step. Two types of stool material were used for three sets of DNA extraction, ...

Molecular Testing (PCR): DNA-based tests can identify specific nematode species. There are also nematode extraction kits you can get for home testing, but they have varying accuracy levels.

Nematodes or roundworms make up a majority of the marine meiofauna — minute invertebrates ... Make every measurement, be precise with every morphology, and perform molecular DNA extraction and ...

If you'd like to learn more about your health, heritage and family history, an at-home DNA test can help you do just that. Justin Jaffe is the Managing Editor for CNET Money. He has more than 20 ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows.

The team conducted molecular and morphological analyses on nematode populations collected from maize fields across New Zealand. Using DNA sequencing with ITS, LSU (D2/D3) and COX1 regions ...

DNA methylation is the covalent addition of methyl groups to DNA bases, typically the cytosine of CpG dinucleotides. It is catalyzed by methyltransferase enzymes using a S-adenosyl methionine ...

A 2015 report published by a private genomics testing company found that 2% of 345 hot dogs tested contained traces of human DNA. However, it was unclear whether that report was a peer-reviewed ...

The number of home DNA test kits offering nutrition and diet advice matched to your genes is growing. They’re based on the idea that each of us responds to foods differently, in part due to our ...

Biologists have discovered that the nematodes respond differently to carbon dioxide at different stages in their life cycle, which could help scientists find ways to prevent or cure infections by ...

The dwindling availability of insecticide seed treatment and nematicides has paved the way for pest control using entomopathogenic nematodes. Following successful trial work in key high-value ...

Soybean cyst nematodes have been present in every Iowa county since 2017 and new survey results show the costly crop pests continue to spread to more counties across the country and in Canada. Greg ...
