Knots are indispensable tools for such human activities as sailing, fishing and rock climbing, (not to mention, tying shoes). But tying a knot in a lacelike strand of DNA, measuring just billionths of a meter in length, requires ...

(Phys.org)—Genome editing for purposes of replication and repair is handled by enzymes called endonucleases, which cleave DNA strands at very specific sites. These are called "restriction sites," composed of palendromic ...
Researchers from the University of Cambridge and the Babraham Institute have found that a naturally occurring modified DNA base appears to be stably incorporated in the DNA of many mammalian tissues, possibly representing ...

(Phys.org)—DNA bricks are an odd phenomenon. They are nanostructures built from synthetic, single-strand DNA that self-assemble into 3D structures. Several years ago, researchers at Wyss Institute at Harvard demonstrated ...
The molecular machines that copy DNA in a living cell are amazingly fast and accurate at pairing up the correct bases—G with C and A with T—into each new double helix.
