, a combination of selected DNA and RNA--the chemical that translates the DNA's genetic code into a protein which the body can use--acts like a chemical instruction to the cell itself to alter the gene in the desired way.
When used in clinical applications, this molecule is packaged with a delivery system and then is administered into the subject and ultimately the chimeraplast
binds selectively to the portion of the target gene to be modified.
were cleverly introduced into the nuclei of liver cells, where the chimeraplasts
' sequence matched almost perfectly with a complementary sequence on a chromosome.
