  • Tumor
  • The specific function of the paired box gene 7 is unknown but speculated to involve tumor suppression since fusion of this gene with a forkhead domain family member has been associated with alveolar rhabdomyosarcoma. (wikipedia.org)
  • chromosomal
  • Here, we report the first evidence that a distinct category of chromosomal translocations observed in human tumours-those targeting 1q12 satellite DNA-can directly mediate such perturbations by promoting the formation of aberrant heterochromatic foci (aHCF). (cnrs.fr)
  • Here we describe a detailed characterization of the human PcG complex in terms of cellular localization and chromosomal association. (nih.gov)
  • Sequence variants of the chromosomal region Xp11.22 are also predicted to confer susceptibility to prostate cancer in humans. (wikipedia.org)
  • Mitosis
  • All chromosomes normally appear as an amorphous blob under the microscope and only take on a well-defined shape during mitosis. (wikipedia.org)
  • It is entirely coincidental that the Y chromosome, during mitosis, has two very short branches which can look merged under the microscope and appear as the descender of a Y-shape. (wikipedia.org)
  • When the diploid cells are duplicated and condensed during mitosis, the result is about 120 micrometers of chromosomes. (wikipedia.org)
  • genetics
  • Not only do Mormon apologists have to deal with human genetics, they also have to explain the genetics of certain intestinal bacteria and domesticated dogs. (godandscience.org)
  • The Institute now employs around 900 people[citation needed] and engages in four main areas of research: Human genetics, pathogen genetics, mouse and zebrafish genetics and bioinformatics. (wikipedia.org)
  • Human Molecular Genetics. (wikipedia.org)
  • Species
  • I think human people should get more deference than ones from other species, and that is how it generally happens in society. (sciforums.com)
  • This project aims to determine the extent of chromosome rearrangements between rock-wallaby species in northern Queensland, where speciation appears to be caught in the act. (edu.au)
  • The advances in technology allow the Sanger Institute to carry out sequencing of the genomes of individual humans, vertebrate species and pathogens, at an ever-increasing pace and reducing cost. (wikipedia.org)
  • Y is the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction. (wikipedia.org)
  • sperm
  • Men on the other hand have an X and a Y. So, each of their sperm carries one of the 2 sex chromosomes, which sex chromosome is in the sperm that fertilizes the egg dictates the baby's sex. (parents.com)
  • When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes. (wikipedia.org)
  • The sperm and egg, or gametes, each have 23 unpaired chromosomes, and red blood cells have no nucleus and no chromosomes. (wikipedia.org)
  • variation
  • Due to the copy number variation chromosomes of different sizes can be combined in a new cell. (wikipedia.org)
  • a parent is unknowingly the carrier of a chromosome with a copy number variation and passes it at conception to the child, with different consequences for the child. (wikipedia.org)
  • amino acids
  • Human chorionic gonadotropin is glycoprotein composed of 237 amino acids with a molecular mass of 36.7 kDa, approximately 14.5 αhCG and 22.2kDa βhCG. (wikipedia.org)
  • DUF4596 on human PRP36 is 47 amino acids long, has an isoelectric point of 3.77, and is almost completely conserved across mammals. (wikipedia.org)
  • determination
  • She realized that the previous idea of Clarence Erwin McClung, that the X chromosome determines sex, was wrong and that sex determination is, in fact, due to the presence or absence of the Y chromosome. (wikipedia.org)
  • For example, the platypus relies on an XY sex-determination system based on five pairs of chromosomes. (wikipedia.org)
  • Platypus sex chromosomes in fact appear to bear a much stronger homology (similarity) with the avian Z chromosome, and the SRY gene so central to sex-determination in most other mammals is apparently not involved in platypus sex-determination. (wikipedia.org)
