While it can be helpful for learners to begin with the linear presentation of how stretches of DNA form genes, this ...

DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus.

Here we present the crystal structure of MutS in complex with a 30-base pair (bp) DNA oligomer with a G·T mismatch at position 9. The non-conserved 53 amino acids at the carboxy terminus were ...

Imagine if you could "print" a tiny skyscraper using DNA instead of steel. That’s what researchers at Columbia and Brookhaven ...

New Twisted 'Knot' Human DNA Structure Discovered—and It Looks Nothing Like the Double Helix. Published Apr 23, 2018 at 12:58 PM EDT Updated Apr 23, 2018 at 1:53 PM EDT. By .

For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double helix we learned about in school.

In DNA discovery lore, it was Photograph 51—taken in May 1952—that revealed so much about DNA’s helical structure. Four decades later, ...

Other forms of both DNA and RNA exist that subvert the classical structures of these nucleic acids. Z-DNA While the structure of DNA you will see above – and in any biology textbook you might care to ...

James Watson and Francis Crick revealed the structure of DNA — the genetic instructions in all living things — 70 years ago in the journal Nature. Watson and Crick could not have succeeded ...

DNA is widely accepted to be formed of two strands that wind around one another, known as a double helix, but it is possible for DNA to change shape and structure.
