Here we show that 5fC is distinct from 5mC, 5hmC and 5caC in its pronounced impact on the structure of the DNA double ... 5′-adjacent G′7 (W1), and another links the same formyl group to the 3 ...

The DNA is contacted in both the major and minor grooves by two loops that penetrate into the middle of the DNA helix ... (∼32.5 mg ml-1) and annealed DNA (5′-AACTGCGCAGTT-3′) were ...

C ertain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred to as non-B DNA—have been implicated as regulators of cellular ...

When most of us think of DNA, we think of that iconic double helix shape. But when you zoom ... DNA molecule," Harris said in a statement. The 3 billion base pairs that make up human DNA ...

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 ...

which set out to sequence the more than 3 billion letters in our genetic code. Biologist James Watson and physicist Francis Crick realized our DNA molecules form a three-dimensional double helix ...

ethylene glycol and polyethylene glycol (each approximately the size of one DNA double helix, 2 or 3 nanometers). "We wanted to have a wide variety of molecules where some cause dehydration ...

DNA consists of two strands, arranged in a double helix. These strands are made up of subunits called nucleotides. Each nucleotide contains a phosphate, a 5-carbon sugar molecule ... sugar gives DNA ...

National DNA Day celebrates the “discovery of the DNA double helix structure,” which is used in genealogy to trace your family ancestry. For 2023, the holiday marks 70 years since the ...

The average dividing cell must copy—perfectly—3.2 billion base pairs of ... doesn’t start correctly. For DNA to be copied, the DNA double helix must open up, and the resulting single strands ...

Why is DNA almost always a right-handed helix? Same with alpha helices ... an order-2 sphinx can be made from 4 sphinx tiles, an order-3 sphinx can be made from 9, and so on.
