Credit: Kateryna Kon/Science Photo Library/ What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and answer questions ...

One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double helix. Double-strand breaks ... the broken DNA ends or by using another DNA ...

But surprisingly, the single-molecule images showed major variations in the depths and grooves in the double helix structure. Above: An image of the DNA double helix structure taken with the AFM ...

But now, using an electron microscope, scientists have taken a highly vivid snapshot of a tightly packed bundle of DNA — perhaps the best glimpse yet of this life-giving molecule.

Dr Harris said: "When Watson and Crick described the DNA double helix, ... Designer molecule shines a spotlight on mysterious four-stranded DNA. Sep 9, 2015. DNA falls apart when you pull it.

DNA is probably best known for its iconic shape — the double helix that James Watson and Francis Crick first described more than 60 years ago. But the molecule rarely takes that form in living cells.

DNA has an oscillating double-helix structure. ... They then bombarded the piece of DNA with extremely short laser pulses. A special type of camera registered how the molecule fluoresced.

When most of us think of DNA, we think of that iconic double helix shape. But when you zoom out, DNA gets a lot more complicated. "When Watson and Crick described the DNA double helix, they were ...

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 ...

Researchers have imaged in unprecedented detail the three-dimensional structure of supercoiled DNA, revealing that its shape is much more dynamic than the well-known double helix. Researchers have ...
