The latest chapter proved that DNA has nothing to do with owning a sharingan. Tobimara was right, awakening a sharingan only requires Uchiha chakra. So Uchiha chakra is like Bijuu chakra in terms of using. Kakashi now has Uchiha chakra so he isn't different from uchihas, except in DNA what isn't important.
I guess thats also why Orochimaru wanted an living Uchiha body instead of obtaining DNAs from uchihas.
