No. of bitstreams: 0 Previous issue date: 2021-09-01; B chromosomes occur in different species of the small characid fishes of the genus Moenkhausia. These supernumerary elements, that do not recombine with chromosomes of the standard A complement and follow their own evolutionary mechanism vary in number, morphology, and distribution. Here, we show karyot...

Contributions of cytogenetics to cancer research
Oliveira-Junior, Robson José de; Goulart Filho, Luiz Ricardo; Bastos, Luciana Machado; Alves, Dhiego de Deus; Silva, Sabrina Vaz dos Santos eThe two conflicting visions of tumorigenesis that are widely discussed are the gene-mutation hypothesis and the aneuploidy hypothesis. In this review we will summarize the contributions of cytogenetics in the study of cancer cells and propose a hypothetical model to explain the influence of cytogenetic events in carcinogenesis, emphasizing the role of aneuploidy. The gene mutation hypothesis states that gene-sp...
Comparacao citogenetica de duas populacoes de Astyanax scabripinnis (Pisces, Ch...
Cristina dos Santos, Ana; Morelli, SandraForam realizadas análises citogenéticas em espécimens de Astyanax scabripinnis provenientes de duas populações da região do triângulo mineiro (Campina Verde - MG). As duas populações apresentaram número diplóide igual a 50 cromossomos. A impregnação pela Prata evidenciou um sistema de NORs múltiplas. Os blocos de heterocromatina constitutiva foram localizados na região telomérica de alguns cromossomos subtelocê...
