What is DNA, and how does it work ... pairs is a compound molecule called a nucleic acid. Living organisms are constantly ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...

Except for identical twins, each person's DNA is unique. This is why people can be identified using DNA fingerprinting. DNA can be cut up and separated, which can form a 'bar code' that is ...

DNA methylation is a fundamental epigenetic mechanism in which a methyl group is added onto a nucleotide, commonly cytosine. DNA methylation affects many biological processes, including gene ...

Researchers at the University of Toronto have invented a new method that uses DNA sequencing to measure metabolites. This ...

Researchers have previously tried sticking down one end of a DNA molecule to stretch it out, but found that the thermal fluctuations could still cause movement and blurring. "Stretching DNA refers ...
