Fortunately, the models yielded different predictions about the distribution of old versus new DNA in newly divided cells, ... every new strand of DNA would be built with 14 N rather than 15 N.

The DNA is wrapped around histones -- protein structures that are sometimes depicted as discs. Histones carry a slight positive charge, and DNA carries a slight negative charge.

The exact moment DNA starts to unravel has been seen by scientists for the first time, exposing a chemical process that is essential for DNA to be the molecule that codes for all life.

Short circular DNA nanotechnology. Comparatively, short circular DNA nanotechnology is created following a series of circularization steps that convert the short linear template strand into a ...

“PDI is like a double agent,” Dr Shadfar explains. “In healthy cells, it repairs DNA and helps prevent disease. But in cancer ...

The DNA polymerases are divided into seven families based on their sequence homology and crystal structure analysis. ... These enzymes work by using RNA as template to synthesize a DNA strand ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a ...

So in effect, when hydrogen atoms leap from one side of a DNA strand to the other, they move as a single proton, hence scientists refer to the phenomenon as "proton transfer," according to a 2014 ...

The new method, published in Nature last week, is more efficient, storing 350 bits at a time by encoding strands in parallel. Rather than hand-threading each DNA strand, the team assembles strands ...

DNA, or deoxyribonucleic acid, is fundamental to your growth, reproduction, and health. Read about its basic function and structures.

The technique uses a long strand of DNA with a set sequence—the template—and a bunch of shorter, premade DNA molecules that can base pair with specific spots on the template—the bricks.
