1. Organizer models, gender and moral in the conflicts resolution between youngs in the school / Modelos organizadores, genero e moral na resolução de conflitos entre jovens na escola
O objetivo desta pesquisa foi investigar os modelos organizadores elaborados por jovens, desde uma perspectiva de gênero, numa situação de conflito interpessoal na escola. Parte-se dos referenciais da Teoria dos Modelos Organizadores do Pensamento, do Paradigma da Complexidade e de perspectivas críticas sobre os estudos de gênero como contribuintes de a

2. Analises citogeneticas em abelhas do genero Melipona (Hymenoptera, Meliponinae)
This work is a contribution to the studies of the cytogenetics of the genus Melipona (Hymenoptera, Meliponini), which were initiated by KERR in 1948. The chromosome number is the same (n=9 e 2n=18) for the 11 species of the genus: Me/ipona marginata, Me/ipona quadrifasciata, Me/ipona bic%r, Melipona compressipes, Me/ipona subnitida, Me/ipona scutellaris, Mel

3. Ribosomal Gene Magnification in Drosophila: A Chromosomal Change
The sex-linked mutant "bobbed" can undergo a rapid phenotypic reversion during a prescribed series of outcrosses. The experiments reported here distinguish between two general genetic models. The first is that the phenotypic change results from the changing genetic background brought about by the outcrosses. The second is that the phenotypic change results f

4. Rescue of atypical protein kinase C in epithelia by the cytoskeleton and Hsp70 family chaperones
Atypical PKC (PKCι) is a key organizer of cellular asymmetry. Sequential extractions of intestinal cells showed a pool of enzymatically active PKCι and the chaperone Hsp70.1 attached to the apical cytoskeleton. Pull-down experiments using purified and recombinant proteins showed a complex of Hsp70 and atypical PKC on filamentous keratins. Transgenic a

5. Restricted chromosomal silencing in nucleolar dominance
Failure of one parent's chromosomes to organize nucleoli in an interspecific hybrid is an epigenetic phenomenon known as nucleolar dominance. Selective gene silencing on a scale of millions of bp is known to be involved, but the full extent to which nucleolus organizer region (NOR)-bearing chromosomes are inactivated beyond the NORs is unknown.

6. Zinc finger as distance determinant in the flexible linker of intron endonuclease I-TevI
I-TevI, the phage T4 td intron-encoded endonuclease, recognizes a lengthy DNA target and initiates intron mobility by introducing a double-strand break in the homing site. The enzyme uses both sequence and distance determinants to cleave the DNA 23–25 bp upstream of the intron insertion site. I-TevI consists of an N-terminal catalytic domain and a C-termin
