    • There is disclosed a process for the incorporation of DNA into a microorganism that, because of natural restrictions in the organism, normally would prevent or limit the incorporation of the DNA. The process involves the selection of an intermediate host organism that has no restrictions to the incorporation of DNA. The DNA is then transferred into the intermediate host which is readily accomplished because there are no restrictions. The DNA is then isolated from the intermediate host and transferred into the target organism. Using this process the natural restrictions of the host organism are circumvented and DNA is transferred from a source organism to a target organism that normally would not be possible. In this manner desirable characteristics from the source organism can be imparted into the target organism.
    • 公开了将DNA并入微生物的方法,由于生物体中的天然限制,通常会阻止或限制DNA的引入。 该方法涉及对并入DNA没有限制的中间宿主生物的选择。 然后将DNA转移到容易实现的中间宿主中,因为没有限制。 然后将DNA从中间体宿主分离并转移到靶生物中。 使用这个过程,规避宿主生物的自然限制,DNA从源生物转移到通常不可能的目标生物体。 以这种方式,可以将来自源生物体的所需特征赋予目标生物体。
