Insertion of the plasmids at the MSH2 locus, creating duplications was confirmed by genomic Southern blot and PCR analyses (G. Manthey and A. Bailis – unpublished observations).
They know where the system breaks down, where it creates duplication, and how it can better meet needs.
The critics contend that the system creates duplication, including more top jobs like superintendent or police chief.
But Dennis Bolt, of the Western States Petroleum Association, said that the agency was overstepping its authority and that the fee was likely to create duplication and confusion with the suite of climate-change measures being developed by the state's Air Resources Board.
According to this model, new genes are created by duplications, including tandem duplication and block (multigene) duplication (birth).
These strong correlations might have to do with the fates of the duplicated genes, and how redundancy, or lack thereof, created by duplication interplays with fitness effects of the gene pairs.
And the initial designers of a regulatory structure would be unlikely to create the duplication and overlaps of jurisdiction that this defense supports although complex systems (think of a passenger jet airplane) often have duplication and redundancies deliberately embedded so as to provide backstopping for component failures (such as the regulatory problems just described).
Initially, the case study presents different ways the model could be created, including duplication affected versions, but also presents models using sharing strategies.
Taken together, our results suggest her8a was created by duplication events which allowed functional diversity to develop within the paralogues.
Tandemly arrayed genes are thought to be subject to birth-and-death evolution, in which new genes are created by duplication.
