After one DNA molecule was trapped on the surface treated by APTES, the DNA molecule was stretched by pressure flow and ...

These bases are the rungs of the DNA ladder. (It takes two bases to form a rung -- one for each side of the ladder.) A sugar molecule, a base, and a phosphate molecule group together to make up a ...

There's a lot of DNA within the nucleus -- about six feet if you could unravel it and stretch it out end to end. To fit such a long molecule within the tiny space of the nucleus, DNA bends and ...

The way DNA folds inside the nucleus of brain cells may hold the key to understanding a devastating form of brain cancer ...

A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

One of the challenges of fighting pancreatic cancer is finding ways to penetrate the organ's dense tissue to define the ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

DNA sequencing is a laboratory method used to determine the sequence of a DNA molecule. The method was developed by Frederick Sanger in 1975, who was later awarded the Nobel Prize in chemistry in ...

One of the challenges of fighting pancreatic cancer is finding ways to penetrate the organ's dense tissue to define the margins between malignant and normal tissue. A new study uses DNA origami ...

Francis Crick and James Watson with a model of the DNA molecule At midday on 28 February 1953, Francis Crick and James Watson walked into The Eagle pub in Cambridge and announced “We have ...
