  • Genomic
  • Lastly, heritability and stability of a rearranged chromosome suggest a potential for enduring genomic novelty. (elifesciences.org)
  • Genomic DNA treatment with the Eco RI restriction enzyme, and Southern blot analysis using an 18S rDNA probe from maize, demonstrated that individuals with B chromosomes displayed bands which were not present in individuals that did not bear this chromosome (RM Brito and SG Pompolo, unpublished data). (scielo.br)
  • genes
  • With the human DNA probe, signals were detected in the major sites of the ribosomal genes on chromosomes 5I (7H) and 6I (6H) only when the chromosome preparations were obtained using an optimized technique with obligatory pepsin treatment followed by hybridization. (deepdyve.com)
  • The deleted region of chromosomes 6 harbors almost 1.400 and that of chromosome 13 more than 500 genes, the duplicated region of chromosome 20 contains about 700 genes. (biomedcentral.com)
  • Skin fibroblasts, derived from a 9 years old NBS patient showed a mosaic of normal diploid cells and those with a complex, unbalanced translocation, leading to the loss and duplication of hundreds of genes. (biomedcentral.com)
  • a researcher at the University of Minnesota College of Biological Sciences discovered that the linear arrangement of genes on a chromosome corresponds to the development of body segments in fruit flies ? (thefullwiki.org)
  • Positional cloning of such genes is dependent on high-resolution methods that can detect losses and gains of chromosome segments. (biomedcentral.com)
  • somatic
  • Study of the maize ( Zea mays L.) somatic chromosomes (2 n = 20) has been difficult because of a lack of distinguishing characteristics. (pnas.org)
  • However, the identification of somatic chromosomes has been difficult because the highly condensed chromatin structure conceals the fine details that are used for chromosome identification at the pachytene stage, such as cytologically observable knobs, heterochromatic regions, arm ratios, and total chromosome length ( 5 ). (pnas.org)
  • These studies reaffirmed that chromosome structure and behavior in somatic and germ cell divisions were common to all plants and animals. (biomedcentral.com)
  • karyotypic
  • Macrotus californicus chromosome paints will be a valuable tool for documenting the pattern of karyotypic evolution within Phyllostomidae radiation. (biomedcentral.com)
  • Integration of empirical data with proposed models of chromosome evolution was performed to understand the probable conditions for Tonatia 's karyotypic evolution. (biomedcentral.com)
  • The trajectory of reorganization of chromosome blocks since the common ancestor of Glossophaginae and Phyllostominae subfamilies suggests that multiple tandem fusions, as well as disruption and fusions of conserved phyllostomid chromosomes were major drivers of karyotypic reshuffling in Tonatia . (biomedcentral.com)
  • Because of their high levels of karyotypic variation, phyllostomid bats are an ideal group to investigate the mechanisms responsible for chromosome evolution and stasis. (biomedcentral.com)
  • lineages
  • The apomictic lineages of Boechera occur at both the diploid and triploid level and show signs of a hybridogenic origin, resulting in a modification of their chromosome structure, as reflected by alloploidy, aneuploidy, substitutions of homeologous chromosomes, and the presence of aberrant chromosomes. (frontiersin.org)
  • mitosis
  • The DCC contains a subcomplex (condensin I DC ) similar to the evolutionarily conserved condensin complexes which play fundamental roles in chromosome dynamics during mitosis and meiosis. (biomedcentral.com)
  • proteins
  • Using 3D FISH microscopy to measure the volumes of X and chromosome I territories and to measure distances between individual loci, we show that hermaphrodite worms deficient in DCC proteins have enlarged interphase X chromosomes when compared to wild type. (biomedcentral.com)
  • Condensin I DC , a subcomplex within the DCC, contains two SMC (structural maintenance of chromosome) proteins (DPY-27 and MIX-1) and three CAP (chromosome-associated polypeptide) proteins (DPY-26, DPY-28, and CAPG-1). (biomedcentral.com)
  • Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions. (thefullwiki.org)
  • Although the interior of the nucleus does not contain any membrane-bound subcompartments, its contents are not uniform, and a number of subnuclear bodies exist, made up of unique proteins, RNA molecules, and particular parts of the chromosomes. (wikibooks.org)
