NTR is universally distributed from bacteria to mammals, but two different forms have evolved.
If the traits of interest to evolutionary psychologists are universally distributed, then we should expect to find them in all humans.
Volutin granules appear to be universally distributed and are morphologically and chemically identical to acidocalcisomes, which are electron-dense granular organelles rich in calcium and phosphate, whose functions include storage of phosphorus and various metal ions, metabolism of polyphosphate, maintenance of intracellular pH, osmoregulation and calcium homeostasis.
Molecular biological measurements of the DNA that codes for components of the ribosomes (organelles that are universally distributed) consistently find fungi to be extremely different from plants.
Of these, 133 genes were coincident with the proposal of a minimum number of genes for a self-sustainable cell by Gil et al. [ 27] and composed what we called the 'essential' core, whose genes not only are universally distributed but also suspected to have an essential functional role.
Some of these are restricted to certain organisms, such as the chloroplasts, whereas others seem to be universally distributed, although with a large degree of variation and secondary modifications.
This enzyme may have become specialized posterior to the divergence of the LCA, from a broad-specificity ancestor, similar to the HGPRTase (PRTases) (2.4.2.8); indeed, this enzyme was found to be universally distributed among the three cellular domains and exhibits a similar catalytic mechanism.
As above remarked, this clay may be said to be universally distributed over the floor of the oceanic basins; but it only appears as a true deposit at points where the siliceous and calcareous organisms do not conceal its proper characters.
It is an essential part of the complex and it seems to be universally distributed among eukaryotes [51], [52].
