Method of modifying the DNA of an organism, DNA sequence, method of detection and isolation of a gene capable of modifying the DNA of an organism and organisms comprising modified DNA

摘要

Method of modifying DNA by subjecting the DNA to a mutation-inducing treatment. The method includes the steps of bringing the DNA to be mutated and a gene encoding a mutation-inducing non-DNA polymerase protein together in cells, growing the cells in the presence of a stress factor, and selecting the mutant cells which have developed a desirable trait in the presence of the stress factor.
