Fact Sheets about Genomics Cloning Fact Sheet En Español Cloning Fact Sheet The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity. The copied material, which has the same genetic makeup as the original, is referred to as a clone. Yes. There's two specific skills that infertility doctors have that are necessary for cloning. One is micro-manipulation of embryos. In this case, to take a human egg, to remove the nucleus, and DNA cloning is the process of making multiple, identical copies of a particular piece of DNA. In a typical DNA cloning procedure, the gene or other DNA fragment of interest (perhaps a gene for a medically important human protein) is first inserted into a circular piece of DNA called a plasmid. To make a clone, scientists transfer the DNA from an animal's somatic cell into an egg cell that has had its nucleus and DNA removed. The egg develops into an embryo that contains the same genes as the cell donor. Then the embryo is implanted into an adult female's uterus to grow. Human Cloning. Human reproductive cloning - producing a genetic copy of an existing person using somatic cell nuclear transfer - has never been done. Many scientists believe that it can never be safe. In opinion polls , , overwhelming majorities consistently reject its use. Dom Burgess investigates whether we could clone humans in the future and the current state of artificial and reproductive cloning processes. wvLdH.
