1. The researchers encased marker genes in liposomes _ microscopic man-made spheres of fatty material. 2. Two others have just the marker gene , Campbell said. 3. Human iChon cells expressed marker genes for chondrocytes ( type II collagen ) but not fibroblasts. 4. These animals were transfected but contained a marker gene " not " the cloned gene of interest. 5. Monsanto made the first transgenic plant, a petunia with a marker gene from a bacteria, in 1983. 6. (4 ) The observable characteristic of transgenic cells may be a transient expression of the marker gene . 7. Five pregnancies resulted, and three health males were born, including ANDi, whose cells contained the marker gene . 8. These genes include cancer marker genes and genes involved in cell adhesion, migration, and metastasis . [ 4] 9. DESIRED TRAITS : Visual marker gene . 10. The DNA used in these preliminary experiments carried a marker gene , which was expressed, but no known human genes.
