  • karyotypes
  • We present an overview of the various conceptual approaches which can be largely divided into two classes: Simple bar codes designed for chromosome identification and complex bar codes for high resolution aberration screening of entire karyotypes. (uni-muenchen.de)
  • A genetic test is the analysis of human deoxyribonucleic acid (DNA), ribonucleic acid (RNA), chromosomes, and proteins to detect heritable disease-related genotypes, mutations, phenotypes, or karyotypes (standard pictures of the chromosomes in a cell) for the purposes of diagnosis, treatment, and other clinical decision making.

  • chromatin
  • High resolution ordering of YAC contigs using extended chromatin and chromosomes. (currentprotocols.com)
  • Previous work has demonstrated a more decondensed large-scale chromatin structure and a more internal nuclear position for gene-rich versus gene-poor chromosome regions. (biologists.org)
  • Here, we show that large-scale chromatin opening and changes in intranuclear positioning of chromosome regions can be induced by normal levels of endogenous transcription factors acting on mammalian regulatory sequences. (biologists.org)
  • Our results indicate that both large-scale chromatin decondensation and changes in nuclear positioning as observed for large, complex gene-rich chromosome regions can be reproduced by endogenous regulatory sequences acting within simple repetitive transgene arrays. (biologists.org)

  • phylogenetic
  • Recent phylogenetic results have demonstrated that genome and chromosome reduction in Arabidopsis are derived characteristics from its close relatives with n = 8. (plantphysiol.org)
  • humans
  • In humans, for example, a person's biological characteristics are controlled by the genetic code contained in 23 chromosome pairs. (google.com)
  • samples
  • Samples received within 24 hrs are good because the viability of the cells is lost when the sample is sent late which affects the quality of chromosomes. (ccmb.res.in)
