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 ...

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 ...

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 ...
