11. "G . intestinales " is divided into eight assemblages based on host specificities and genetic divergence of marker genes . 12. Heat shock is used to induce Flp recombinase marker gene expression is activated in dividing cells due to recombination. 13. In the absence of a good marker gene , there was no way of knowing whether control of pollination was adequate. 14. In the current study, Schatten started with 224 monkey eggs, mixing them with a virus that carried the marker gene . 15. Comparisons of sequences for certain mitochondrial marker genes indicate that some elanid kites split early from the rest of the Accipitridae. 16. The proposed laboratory experiments would involve inserting a so-called marker gene into the smallpox virus that glows green under fluorescent light. 17. In the current study, Schatten started with 224 monkey eggs, mixing them with a neutralized virus that carried the marker gene . 18. But scientists say the marker gene product is broken down in the digestive tract and thus cannot function in the human body. 19. Two other lambs were born a couple of days ago and are expected to have the human gene and the marker gene . 20. To accomplish this, a marker gene is co-transfected, which gives the cell some selectable advantage, such as resistance towards a certain toxin.
