Folding


Definition:

  • (p. pr. & vb. n.) of Fold
  • (n.) The act of making a fold or folds; also, a fold; a doubling; a plication.
  • (n.) The keepig of sheep in inclosures on arable land, etc.

Example Sentences:

The effect of heparin was dose-dependent and specific (it was not duplicated by other glycosaminoglycans).
  • (8) The following conclusions emerge: (i) when the 3' or the 3' penultimate base of the oligonucleotide mismatched an allele, no amplification product could be detected; (ii) when the mismatches were 3 and 4 bases from the 3' end of the primer, differential amplification was still observed, but only at certain concentrations of magnesium chloride; (iii) the mismatched allele can be detected in the presence of a 40-fold excess of the matched allele; (iv) primers as short as 13 nucleotides were effective; and (v) the specificity of the amplification could be overwhelmed by greatly increasing the concentration of target DNA.
