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?

Keep reading to discover more about the structure of DNA, what it does, ... making up the “backbone” of the DNA strand. Each sugar in a nucleotide has a nitrogen base attached to it.

Nucleotides: DNA is composed of four types of nucleotide building blocks – adenine (A), thymine (T), guanine (G), and cytosine (C).Each nucleotide consists of a phosphate group, a sugar group ...

Wang et al. describe the crystal structure of an Argonaute protein bound to a single-stranded, 21-nucleotide DNA that mimics the strand used to silence gene expression.

The twisted double strand structure -- the famed double helix -- unwinds and the strands separate. ... Often this copying process makes errors, so that the wrong nucleotide is placed in position.

The structure is about 22 nanometers in overall diameter. ... Shih and Joyce constructed a 1669-nucleotide strand of DNA that they designed to have a number of self-complementary regions, ...

Nucleotide Excision Repair. NER is a multistep process [] that seems to come into operation to repair such DNA damage as the distinct helical distortion caused by ultraviolet-induced photoproducts ...

Considering a single strand of DNA or RNA, one end is designated as the 5′-end (five prime end), because in the chemical structure of the molecule it frequently has a phosphate group attached to ...

The twisted double strand structure -- the famed double helix -- unwinds and the strands separate. ... Often this copying process makes errors, so that the wrong nucleotide is placed in position.
