11. These tests can also confirm the chromosomal location and copy number of the inserted gene. 12. The copy number of this gene varies among individuals. 13. Several mutants of PFF1 which affect the copy number of the plasmid have been identified. 14. This gene and the gene encoding defensin, alpha 1 are both subject to copy number variation. 15. Thus, C4 genes have a complex pattern of variation in gene size, copy number , and polymorphisms. 16. Ethidium bromide has also been used extensively to reduce mitochondrial DNA copy number in proliferating cells. 17. This increases the copy number of the gene. 18. Molecular inversion probe technique can also be used for copy number variation ( CNV ) detection. 19. The result of this spontaneous change in the structure of DNA is a copy number variation. 20. Included on the page is the copy number ( for example : 1193 / 1200 ).
