TECHNIQUE FOR MAKING HEREDITARY SUBSTANCE VISIBLE

摘要

A technique for the visualization of mammalian genetic material in living germ cells, one-cell fertilized eggs and pre-implantation embryo cells is disclosed. The cells are incubated with a fluorescent dye and the stained DNA is visualized by exposing the cell to ultraviolet light. A process of genetic manipulation is also disclosed which comprises transferring DNA into the above-mentioned cells and embryos in which the transferred DNA and/or the cell's own DNA is visualised by the fluorescence technique.
