Often it is found as an inverted repeat with a characteristic core [ 4], the Correia Repeat Enclosed Element (CREE) [ 5], which is most commonly 153 157 bp or 104 108 bp.
The Correia Repeat Enclosed Element (CREE) of the Neisseria spp., with its inverted repeat and conserved core structure, can generate a promoter sequence at either or both ends, can bind IHF, and can bind RNase III and either be cleaved by it or protected by it.
For each element along the path, we perform the above ray-tracing test and calculate the distance (d) between the current photon position (p) to the exit point (px) of the enclosing element along the propagation vector (c).
As the photon moves along its trajectory, the photon packet weight is attenuated exponentially based on the Beer-Lambert law [ 1] using the absorption coefficient (μ a) of each enclosing element.
Each cell in this model is an individual unit containing several sub-cellular elements, such as the elastic plasma membrane, enclosed viscoelastic elements that play the role of cytoskeleton, and the viscoelastic elements of the cell nucleus.
The translation of Control elements is more complicated, because they are translated into a transition or a reaction depending on enclosed Control elements.
Each cell in this model is an individual unit containing several subcellular elements, such as the plasma membrane, enclosed by viscoelastic elements that play the role of cytoskeleton, and the viscoelastic elements of the cell nucleus.
Hereafter, parentheses in construct designations enclose the elements flanked by the frt or lox sites.
To produce a construct enclosing all elements of the regulatory region a (-1895/+106) fragment, containing proximal enhancer and promoter region of vole Oct4 gene, was cloned into plasmid pDE2 at HindIII site (pDEH6 construct).
