DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Nucleosomes are repetitive building blocks introduced in the monotonous linear structure of double ... crosslinked by the covalent backbone of a single DNA molecule. The spontaneous formation ...

In its structure, DNA contains a pattern for producing amino ... Two nucleotides together form a base pair; the sugars and phosphates form a "backbone," along which the base pairs are strung.

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For ...

Laying the Groundwork: Levene Investigates the Structure of DNA Meanwhile ... discovery of the sugar-phosphate backbone of the DNA molecule was still years away. The large number of molecular ...

This diagram depicts the chemical structure of pyrimidine ... The remaining positions are occupied by carbon atoms, forming the backbone of important nucleobases in DNA and RNA. (Image: Public Domain) ...

DNA is negatively charged, due to the phosphate groups in its phosphate-sugar backbone, so histones bind ... irregular and not quite the uniform structure depicted in instructive drawings such ...

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 ...

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren't just skin deep. Inside the body, DNA is literally being torn ...

Combinations of these atoms form the sugar-phosphate backbone of the DNA -- the sides of the ladder, in other words. Other combinations of the atoms form the four bases: thymine (T), adenine (A ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...
