Study Notes

Chromosomal Conditions

  • Triploidy: characterized by an organism or cell having one complete set of extra chromosomes.
  • Polyploidy: a condition where an organism or cell has an exact multiple of a complete set of chromosomes.
  • Trisomy: a condition with a chromosome number of 47, as seen in Down's syndrome.
  • Monosomy: a condition characterized by having a chromosome number of 45, as seen in Turner syndrome.
  • Aneuploidy: a condition where an organism or cell loses or adds one or more chromosomes to the normal set.

Genetic Terminology

  • Nullisomy: a condition where an organism loses one homologous chromosome.
  • Proto-oncogenes: genes that often become active oncogenes, stimulating uncontrolled cell division.
  • Tumor suppressor genes: genes that recognize uncontrolled cell division and act to suppress cell division.
