Researchers have identified the specific structural loops in G-quadruplex DNA that allow it to act as a chaperone, preventing ...

For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...

What scientists long believed were knots in DNA may actually be persistent twists formed during nanopore analysis, revealing ...

This top view of a G-quadruplex shows its structure in the DNA of a human telomere, where they frequently form. Thomas Splettstoesser/Wikimedia Commons In describing the two-stranded structure of DNA, ...

To our immune system, a potentially lifesaving gene therapy can look a lot like a dangerous infection. That's because most genetic medicine uses viruses or double-stranded DNA to deliver genetic ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...

If stretched out, human DNA would be about 2 meters long. For this long strand to fit inside the cell nucleus, which is about 0.01 mm in size, it must be tightly folded. DNA wraps around proteins call ...

The two strands of DNA are antiparallel which means that one strand runs in a 5’ to 3’ direction and the other runs in a 3’ to 5’ direction. This creates the twisting double helix structure of DNA.
