In order to avoid duplication of roles, the existing Secretaría de Función Pública (a public administration ministry) would be eliminated, and its current duties shared between the CNA and the treasury.
Thus, coincident with the expansion in lipid metabolism genes described above, the KstR gene appears to have emerged through gene duplication within the existing gene family of tetR-like transcriptional regulators at the last common ancestor of Mycobacteria and Rhodococcus.
Since the same SAS6 fragments are not capable of supporting the duplication of existing centrioles, the authors suggest that existing centrioles may play a role in shaping the structural integrity of procentrioles.
The ancestral secretin family gene probably arose as part of an existing gene or gene fragment and via exon and gene duplication events generated the existing suite of family members.
This variation can be due to genetic noise (i.e., indels, mobile- and selfish DNA) [ 4, 5], gene loss [ 6, 7], gene duplication [ 8] or modification of some of the existing genes [ 9, 10].
The societies defined human cloning as "the duplication of an existing or previously existing human being by transferring the nucleus of a differentiated, somatic cell into an enucleated human oocyte, and implanting the resulting product for intrauterine gestation and subsequent birth".
Other authors argue, that the evolution of new functions may start with the duplication of an existing gene in a sense a preadaptation for that function, followed by a period of evolution among the gene copies, resulting in the preservation of the most effective variant and the 'pseudogenization' and eventual loss of the remaining copies [ 33].
In a consultation document, the Treasury and the Department for Work and Pensions were critical of the existing arrangements, saying: "There are gaps in the guidance available to consumers and duplication of content between MAS, TPAS and Pension Wise.
