Chromosomal polymorphism involving chromosome pairs 3 and 5 problably due to a pericentric inversion is reported for 60 specimens of Zonotrichia capensis Passeriformes-Aves. The frequency of seven different karyotypes, due to the fact that chromosome 3 is present in the 3 st and 3 sm conditions and chromosome 5 in the 5 st and 5 m conditions, and the significance of this polymorphism are discussed for the genus Zonotrichia and for other genera from the same family Emberizidae.

The momentary dissociation of the repressor that allowssecond backcross is made by crossing B1 individuals a molecule of RNA polymerase to bind to its pro-again with individuals of genotype identical to the moter and initiate transcription.

This is because BACs contain F factor regulatory backbone in biochemistry, the supporting struc- genes that control their replication and maintain ture of atoms in a polymer from which the side their copy number to one or two per cell.

The in vitro susceptibility of three clinical Trichophyton rubrum isolates to griseofulvin and tioconazole, determined by the minimal inhibitory concentration MIC , was 2 and 0. The clinical importance and the possibility of a multidrug resistance MDR -type mechanism being involved in this event is discussed.
