Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can ...

While our DNA is commonly structured as a twisted ladder-shaped double helix, these knots often form in regions with many guanine (G) bases, and help regulate important processes like ...

DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Co-lead author Dr. Zoë Waller (UCL School of Pharmacy) said: “DNA is our genetic material, and its structure usually looks a bit like a twisted ladder called a double helix. This shape is iconic, but ...

To study and understand these zinc finger DNA-protein interactions, we use the extended ladder in the DNA model proposed by Zhu et al. [1]. Considering one single spinless electron in each nucleotide ...

Genes, DNA, and chromosomes make up the human genome. Learn the role they play in genetics, inheritance, physical traits, and your risk of disease.

The software relies on a way to build with DNA described in 2011 by Yan, who was a postdoc with Reif at Duke 20 years ago before joining the faculty at Arizona State. It works by coiling a long DNA ...

What Shape is DNA? If you look at a strand of DNA it looks like a tiny twisted ladder known as a double helix. Double meaning two and helix – meaning a spiral chain. The side rails of those ladders ...

DNA molecules are what we call ‘double stranded’, meaning they are made up of 2 separate chains joined together in the middle. Think of it as being shaped like a ladder; the molecule has 2 side rails ...

What Is DNA? DNA is a molecule in the shape of a double helix, which looks like a twisted ladder. The rungs of the ladder are made of smaller molecules called nucleotides. These nucleotides come ...

Double stranded helix When looking at the structure, Watson and Crick found that DNA is a double stranded helix or a ladder that is twisted.
