hairpin-loop structure
1Hairpin ribozyme — The hairpin ribozyme is a small section of RNA that can act as an enzyme known as a ribozyme. Like the hammerhead ribozyme it is found in RNA satellites of plant viruses. It was first identified in the minus strand of the tobacco ringspot virus… …
2hairpin — 1. The structure formed by a polynucleic acid by base pairing between neighboring complementary sequences of a single strand of either DNA or RNA. 2. The structure seen in a prostaglandin where two segments of the molecule fold back on one… …
3Stem-loop — intramolecular base pairing is a pattern that can occur in single stranded DNA or, more commonly, in RNA. The structure is also known as a hairpin or hairpin loop. It occurs when two regions of the same molecule, usually palindromic (reads the… …
4loop — 1. A sharp curve or complete bend in a vessel, cord, or other cylindrical body, forming an oval or circular ring. SEE ALSO: ansa. 2. A wire (usually of platinum or nichrome) fixed into a handle at one end and bent into a circle at the other,… …
5Nucleic acid tertiary structure — Example of a large catalytic RNA. The self splicing group II intron from Oceanobacillus iheyensis.[1] The tertiary structure of a nucleic acid is its precise three dimensional structure, as defined by the atomic coordinates.[2] …
6RNA structure — The functional form of single stranded RNA molecules frequently requires a specific tertiary structure. The scaffold for this structure is provided by secondary structural elements which are hydrogen bonds within the molecule. This leads to… …
7Beta hairpin — The beta hairpin (or beta beta unit) structural motif is the simplest protein motif involving two beta strands that look like a hairpin. The motif consists of two strands that are adjacent in primary structure oriented in an antiparallel… …
8Lambda phage — Taxobox color = violet name = Enterobacteria phage λ image width = 200px image caption = virus group = I ordo = Caudovirales familia = Siphoviridae subfamily = genus = λ like viruses species = λ Phage Enterobacteria phage λ (lambda phage) is a… …
9Tobacco mosaic virus — Electron micrograph of TMV particles stained to enhance visibility at 160,000x magnification Virus classification Group …
10MicroRNA — The stem loop secondary structure of a pre microRNA from Brassica oleracea. A microRNA (abbreviated miRNA) is a short ribonucleic acid (RNA) molecule found in eukaryotic cells. A microRNA molecule has very few nucleotides (an average of 22)… …
