  2. Hairpin lace - Wikipedia

    en.wikipedia.org/wiki/Hairpin_lace

    Hairpin lace is a lace-making technique that uses a crochet hook and two parallel metal rods held at the top and the bottom by removable bars. Historically, a metal U-shaped eponymous hairpin was used. Hairpin lace is formed by wrapping yarn around the prongs of the hairpin lace loom to form loops, which are held together by a row of crochet ...

  3. Hairpin technology - Wikipedia

    en.wikipedia.org/wiki/Hairpin_technology

    Hairpin technology is a winding technology for stators in electric motors and generators and is also used for traction applications in electric vehicles. In contrast to conventional winding technologies , the hairpin technology is based on solid, flat copper bars which are inserted into the stator stack.

  4. Stem-loop - Wikipedia

    en.wikipedia.org/wiki/Stem-loop

    Stem-loop. Stem-loop intramolecular base pairing is a pattern that can occur in single-stranded RNA. The structure is also known as a hairpin or hairpin loop. It occurs when two regions of the same strand, usually complementary in nucleotide sequence when read in opposite directions, base-pair to form a double helix that ends in an unpaired ...

  5. Short hairpin RNA - Wikipedia

    en.wikipedia.org/wiki/Short_hairpin_RNA

    Short hairpin RNA. Lentiviral delivery of shRNA and the mechanism of RNA interference in mammalian cells. A short hairpin RNA or small hairpin RNA ( shRNA /Hairpin Vector) is an artificial RNA molecule with a tight hairpin turn that can be used to silence target gene expression via RNA interference (RNAi). [1] [2] Expression of shRNA in cells ...

  6. Beta hairpin - Wikipedia

    en.wikipedia.org/wiki/Beta_hairpin

    The beta hairpin (sometimes also called beta-ribbon or beta-beta unit) is a simple protein structural 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 direction (the N-terminus of one sheet is adjacent to the C-terminus of the next ...

  7. Hairpin turn - Wikipedia

    en.wikipedia.org/wiki/Hairpin_turn

    Hairpin turn. A hairpin turn (also hairpin bend or hairpin corner) is a bend in a road with a very acute inner angle, making it necessary for an oncoming vehicle to turn about 180° to continue on the road. It is named for its resemblance to a bent metal hairpin. Such turns in ramps and trails may be called switchbacks in American English, by ...

  8. Rolling hairpin replication - Wikipedia

    en.wikipedia.org/wiki/Rolling_hairpin_replication

    Rolling hairpin replication (RHR) is a unidirectional, strand displacement form of DNA replication used by parvoviruses, a group of viruses that constitute the family Parvoviridae. Parvoviruses have linear, single-stranded DNA (ssDNA) genomes in which the coding portion of the genome is flanked by telomeres at each end that form hairpin loops .

  9. SNP genotyping - Wikipedia

    en.wikipedia.org/wiki/SNP_genotyping

    SNP genotyping is the measurement of genetic variations of single nucleotide polymorphisms (SNPs) between members of a species. It is a form of genotyping, which is the measurement of more general genetic variation. SNPs are one of the most common types of genetic variation. An SNP is a single base pair mutation at a specific locus, usually ...
