But this magnifier doesn't enlarge the view of DNA bases. Rather, it makes billions of identical copies of a small sequence of DNA -- enough copies to allow a machine to detect marked bases within ...

A) DNA polymerase binds to a single-stranded DNA template (blue) and synthesizes a complementary strand of DNA (red). B) When DNA polymerase randomly incorporates a fluorescently labeled ddNTP ...

Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

Over the past decade, reads—the product of DNA sequencing—have been getting longer. Long-read sequencing has allowed scientists to sequence troublesome “dark regions” of the genome that are ...
