Stem Cell – A cell that has the ability to continuously divide and differentiate (develop) into various other kind(s) of cells/tissues
Clone-A cell, group of cells, or organism that is produced asexually from and is genetically identical to a single ancestor. The cells of an individual plant or animal, except for gametes and some cells of the immune system, are clones because they all descend from a single fertilized cell and are genetically identical.
Genetics-The scientific study of the principles of heredity and the variation of inherited traits among related organisms.
Genes-A segment of DNA, occupying a specific place on a chromosome, which is the basic unit of heredity. Genes act by directing the production of RNA, which determines the synthesis of proteins that make up living matter and are the catalysts of all cellular processes
Genome-The total amount of genetic information in the chromosomes of an organism, including its genes and DNA sequences. The genome of eukaryotes is made up of a single, haploid set of chromosomes that is contained in the nucleus of every cell and exists in two copies in all cells except reproductive and red blood cells.
Haemophilia -any of several hereditary disorders, nearly always of males, in which one of the normal blood-clotting factors is deficient, causing serious internal or external haemorrhage from minor cuts and injuries: females with this defective gene are, normally, only carriers.
Gene therapy- the experimental treatment of a disease by the use of techniques associated with genetic engineering, as to modify or replace the disease-causing genes of certain cells.
Germ line- Cells from which gametes are derived.
