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 ...

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 ...

The final DNA strand contains close to 1,700 nucleotides. When the researchers heated and cooled their DNA strands in a test tube, each one folded in on itself and snapped into a virus-size ...

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.
