explainAnswer[1]="A clone is a group of cells or organisms which are genetically identical and have all been produced from the same original cell. The nucleus of a normal cell can be used to create adult cell and therapeutic clones, cells from the inner layer of an embryo are stem cells, and organisms with the same parents are siblings but are not genetically identical.";
explainAnswer[2]="Adult cell cloning is also called <i>reproductive cloning</i>. <i>Embryo cloning</i> involves splitting embryos to make more genetically identical ones, <i>research cloning</i> and <i>reproductive cloning</i> produce a source of DNA matched stem cells.";
explainAnswer[3]="Dolly the sheep was cloned from an udder cell.";
explainAnswer[4]="A mild electric shock is used in adult cell cloning and in therapeutic cloning to trigger division of the new egg/nucleus combination.";
explainAnswer[5]="Somatic cell nuclear transfer is also called <i>biomedical cloning</i>. The name is used to emphasise the fact that the technique has no intention of producing a cloned individual.";
explainAnswer[6]="Therapeutic cloning involves the formation of cloned human embryos. Stem cells are taken from the embryo, insulin producing cells may be produced from the stem cells, and as yet no one has succeeded in making cloned spinal cord.";
explainAnswer[7]="Cloning is anything but easy and reliable&nbsp;–&nbsp;there is a very low success rate in all mammalian species.";
explainAnswer[8]="Cloning primates is proving very difficult indeed.";
