FractionAT[sequence]⟹fraction
determines the fraction of a given sequence composed of As or Ts.
Calculate the fraction of a given DNA or PNA sequence that is composed of A's or T's:
Calculate the fraction of an explicitly defined sequence that is composed of A's or T's:
Calculate the fraction of a given LNAChimera sequence that is composed of any variant of A or T:
Degeneracy defaults to True, meaning the fraction of the degenerate monomer that matches A or T will be included:
Input can be a list of multiple sequences that can be explicitly or implicitly defined:
