When the 5′ end of the siRNA of a RISC complex base-pairs precisely with a target mRNA over a distance of one turn of an RNA helix (10–12 base pairs), this domain of AGO2 cleaves the phosphodiester bond of the target RNA across from nucleotides 10 and 11 of the siRNA

Algebraic transformation of the exponential correlation into an expression based on the decadic logarithm yields the law of Beer–Lambert:

where [d] = 1cm, [c] = 1moldm-3, and [e] = 1dm3mol-1 cm1. e is the molar absorption   coefficient.

where [d] = 1cm, [c] = 1moldm-3, and [e] = 1dm3mol-1 cm1. e is the molar absorption coefficient.

DnaA-ATP in an extended multimeric state promoted by the accessory protein DiaA, which stimulates cooperative binding of DnaA.

DnaA-ATP binds cooperatively to form a helical central core around which oriC DNA is wrapped.
