The organisation of OTC-genes of mutants blocked in OTC-biosynthesis in respect to the parental R6 strain will be revealed . At least some of the mutants lacking the whole OTC-gene cluster could serve as hosts for introduction of foreign genes .
Ispitat će se na molekularnoj razini prisustvo , delecija ili preraspodjela skupine OTC- biosinteznih gena u ranije opisanih R6 mutanata blokiranih u biosintezi OTC- a , jer bi mogli poslužiti kao prikladni recipijenti za homologne/ heterologne gene .
