Low-resolution physical mapping is typically capable of resolving DNA ranging from one base pair to several mega bases. In this category, most mapping methods involve generating a somatic cell hybrid panel, which is able to map any human DNA sequences, the gene of interest , to specific chromosomes of animal cells, such as those of mice and hamsters. The hybrid cell panel is produced by collecting hybrid cell lines containing human chromosomes, identified by polymeras… WebTesting of gene functions in a short period by using stable transgenic tissues is the most important advantage of A. rhizogenes-mediated gene transfer (Kim et al., 2002).
