Boetti's twinning himself and duplicating images runs through this life-long exhibition and seems to remind us of our own duplication in making art: We duplicate our images, feelings, insights -- our beat and rhythm.
It is assumed that a small RNA molecule eventually appeared that was able to catalyze its own duplication.
By the above mechanisms, DNA molecules catalyze not only their own duplication but also dictate the structures of all protein molecules.
Early stages in the evolutionary pathway of cells presumably centred on RNA molecules, which not only present specific catalytic surfaces but also contain the potential for their own duplication through the formation of a complementary RNA molecule.
"The Double" gathers in interest as the action moves from Tertuliano's distress and bafflement at his own duplication to his intervention in the life of his double, the double's retaliation, and the growing involvement of the two women, Maria da Paz and Helena.
They do not own duplication nor printing equipment to mass produce illegal software and, in all cases, were likely the victims of poor software-auditing practices and opportunistic former employees.
Under normal conditions, the regeneration of mouse β cells is mainly dependent on their own duplication.
Evolutionarity distant animals such as flies and roundworms possess one p300/CBP each, although flatworms seem to have acquired their own duplication of p300/CBP.
Transposable elements (transposons) are genomic sequences that either directly encode the mechanism of their own duplication within a genome, or that appropriate a protein product from the cell or another transposable element to achieve mobility.
A network of varying size (three to five members) was constructed, where each protein product interacts with all other protein products immediately after duplication, except its own duplicate (fig. 1).
