A AA in the wavelength region 400 to 850 nm obtained by subtracting the separateiy obtained AA from the composite M P700 -P700 constructed from individual flash-induced absorbance-change transients due to formation of the radical pair - For subtraction of the spectra, a hypothetical factor a was used to represent the fraction of absorbance difference at 700 nm that is due to P700 change Nanosecond flash studies of the absorption spectrum of the photosystem I primary acceptor Aq.

A AAB sequence-controlled radical copolymerization of d-limonene . MALDI-TOF-MS

A Abbreviated reaction sequence for formation of a four-way FfoUiday junction between two homologous DNA duplexes. In step a strands are cut and rejoined with movement of the strands to a roughly antiparallel orientation. The resulting structure is thought to resemble that shown below the four-stranded representation. In step b branch migration takes place, separating the nonhomologous base pairs TA and CG and causing mismatched pairs which will be subject to repair. .

A Abbreviated reaction sequence for formation of a four-way Holliday junction between two homologous DNA duplexes. In step a strands are cut and rejoined with movement of the strands to a roughly antiparallel orientation. The resulting structure is thought to resemble that shown below the four-stranded representation.
