The positional information needed to construct a limb has to function in a three-dimensional coordinate system:

Proximal-distal axis

Anterior-posterior axis

Dorsal-ventral axis

DNA polymerase III holoenzyme assembles in stages, generating an enzyme complex that synthesizes the DNA of both new strands.\

Binding to DNA changes the conformation of the site on B that binds to the clamp loader, and as a result it now has a high affinity for the core polymerase.

First the clamp loader uses hydrolysis ofATPtobindbeta subunits to a template primercomplex.

fluorescence occurs in nanoseconds (ns, 10–9 s); however, photochemistry in photosynthetic organisms occurs more rapidly, in picoseconds (ps, 10–12 s). Thus, when the 1,000‐fold more rapid pathway of photochemistry is available, little fluorescence is observed and photosynthesis proceeds with high efficiency.
