Definitions

Noun
  1. 1
    Any subsequence of nucleic acid, selected from a large random sequence-pool, used to bind to a specific target molecule.

    "Aptamers are oligomers of RNA or DNA that spontaneously fold into specific three-dimensional shapes that can bind defined targets. The specificity of the shape of the binding site arises from the base sequence of the aptamer, which determines the base-pairing pattern of the oligomer."
