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?

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.

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

Nucleotide Excision Repair. NER is a multistep process [9] that seems to come into operation to repair such DNA damage as the distinct helical distortion caused by ultraviolet-induced photoproducts.

When a cell divides, it makes a copy of its DNA instructions for the new cell. The twisted double strand structure -- the famed double helix -- unwinds and the strands separate.

Shih and Joyce constructed a 1669-nucleotide strand of DNA that they designed to have a number of self-complementary regions, which would induce the strand to fold back on itself to form a sturdy ...

DNA, the hereditary material in living organisms, encodes genetic instructions for development and function. We explore its structure, replication, and role in biotechnology.

In contrast, the DNA probe built into the previous chip has a structure that cannot be brought closer to the graphene surface, so it generates a weaker signal upon binding an SNP-containing strand.

There are several interactions present within a strand (intrastrand interactions) and between two strands (interstrand) that stabilize DNA.

When a cell divides, it makes a copy of its DNA instructions for the new cell. The twisted double strand structure -- the famed double helix -- unwinds and the strands separate.
