Competitive Exams: Scientific Terms and Their Definitions

  • 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

Protoncogenes(Normal)MutationOncogenes(Cancerous)

  • Max. Loops in lamp brush chromosomes - Diplotene

  • Mollusca – Hardest shell, softest body, ink glands

  • ABO = Multiple allelism + co-dominance

  • Polio – Attack on dorsal root ganglion of Spinal cord

  • Stea torrhoea – fat indigestion – fat in stool

  • Hematemesis-vomit of blood

  • Hemoptysis coughing up blood..- T.B.
