DNA is the poster child for high-specificity binding. As long as their base sequences match, two complementary strands of DNA can navigate through a sea of biomolecules, find each other, and hold fast ...

A graphic representation of a round, lumpy, blue protein and a single, comblike, purple strand of RNA interacting with a twisted, double, blue strand of DNA that separates where it meets the RNA. A ...

As nucleic acid sequencing has become dazzlingly fast, accurate, and affordable, sequencing a whole genome has gone from a trumpeted accomplishment to another day at the office. Now, metagenomic ...

It used to be that if you wanted to find a DNA sequence in a particular sample, you had to go searching for that specific sequence—you had to fish it out with a hook designed especially to catch it.
