ABSTRACT:
A method of suppressing the expression of a selected gene in a eukaryotic cell the method comprising introducing into the cell (a) a polypeptide comprising a DNA binding portion which binds to a site at or associated with the selected gene which site is present in a plant r animal genome and a chromatin inactivation portion, or (b) a polynucleotide encoding said polypeptide.
