Document Summary
You did similar things in the lab already: from these early experiments, biotechnology progressed to cloning genes, even whole organisms, and producing maybe even ridiculous organisms, for example the red zebra fish that glow under black light. These fish contain a gene for fluorescence from sea anemones: although this seems trivial, similar fish are used to investigate the mechanisms of development, human cloning technology might allow permanent correction of genetic defects. In this process, human embryos are derived from eggs fertilized in culture dishes using sperm and eggs from a man and woman, one or both of whom have a genetic disorder. When an embryo containing a defective gene grows into a small cluster of cells, a single cell would be removed from the embryo and the defective gene replaced using an appropriate vector. The repaired nucleus could then be implanted into another egg (taken from the same woman) whose nucleus had been removed.
