that may arise from the project. History of the Human Genome Project The Human Genome Project (HGP) refers to the international 13-year effort, formally begun in October 1990 and completed in 2003, to discover all the estimated 20,000-25,000 human genes and make them accessible for further biological study. Another project goal was to determine the complete sequence of the 3 billion DNA subunits (bases in the human genome).

begins a cascade of hormones through the animal that are responsible for the oestrus cycle taking place. It is secreted in a pulsating manner with rises and falls in concentrations from the hypothalamus where it is transported to the anterior pituitary gland. It is here that the GnRH controls the release of two protein hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) which are known collectively as gonadotrophins. Because the release of GnRH is in waves, consequently FSH and LH are secreted in waves too. These gonadotrophins are released into the general blood system and are transported to the gonads where they have their major effect.
