  • Human growth hormone (produced by the pituitary gland) = Treat dwarfism
  • Monoclonal antibodies = monospecific antibodies that are made by identical immune cells that are all clones of a unique parent cell. These are proteins produced by the B-lymphocytes of the immune system in response to foreign proteins, called antigens.
  • Myeloma cell = Myeloma is a cancer of plasma cells in the bone marrow.
  • Hybridoma Technology = Making of hybrid cell lines by fusing an antibody-producing B cell with a myeloma cell that is selected for its ability to grow in tissue culture .
  • Hybridomas = produce only one kind of antibody on large scale
  • Anesthesia = without sensation
  • Filter Apparatus of blood = for separating plasma or serum from blood. Juxtaglomerular apparatus
  • Origin of ADIS = Africa Acquired immune deficiency syndrome (AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV) .
  • Duchenne Dystrophy - Abnormal gene on X characteristics in in males
  • Introgression hybrid - one species completely replaced by other
  • introgressive hybridization – the movement of a gene from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species
  • Excessive stiffness - Myoscelerosis (muscles feel tight and contracted than muscles at rest.)
  • Sex linked – genes found on sex chromosome & inherited together
  • Sex limited – expressed only in a part of sex-e. g. milk secretion in female
  • Sex influenced-Boldness (dominant in one & recessive in one)
  • Male more affected then female due to recessive X chromosome in male
