The C proteins involved in cytolysin biosynthesis are split by organism into two different enzyme groups (Fig. 5), further corroborating the ability of only certain cyclodehydratases to modify precursor peptides in this family.
They explored the optimization of fitness as a function of mutation rate in a model of reproducing agents on a toroidal lattice; the agents consumed energy from a "continually augmented external source", and reproduced when they had accumulated sufficient resources to split into two organisms.
Technically called "axial bifurcation," the deformity is a result of the embryo beginning to split into two separate organisms, or twins, but doing so incompletely, Wagner told OurAmazingPlanet.
Hits are split between closely related organisms.
However, many exceptions to this organization exist, as the RNR genes are sometimes separated at different locations on the chromosomes and some organisms contain split RNR genes [ 20, 21, 35, 36].
The pattern of evolution in the DEM depicts the evolution of one group of organisms through splitting and diversification from a single origin to the present day.
12 The guidelines recommend further evaluation of recurrent disease in women with a history of urinary tract surgery, known anatomical abnormalities, immunocompromise, calculi, urea splitting or multidrug resistant organisms, documented abnormalities of flow, pneumaturia, fecaluria, or persistent gross hematuria or asymptomatic microscopic hematuria after treatment of acute cystitis.
However, this was a more daunting task than molecular biologists had expected; developments between 1977 and 1980 showed that, due to the phenomena of split genes and splicing, higher organisms had a much more complex system of gene expression than the bacteria models of earlier studies.
Therefore, at lower taxonomic nodes, the hits get split over multiple closely related organisms.
It appeared that those five organisms can be split into two groups.
