Introduced dna into a mouse embryo

Web•Performed molecular experiments, including RNA isolation, bacterial transformations, DNA extractions, molecular cloning, and microinjection of DNA constructs during mouse embryo transformations. WebDuring the 1970s, the first chimeric mice were produced (Brinster, 1974). The cells of two different embryos of different strains were combined together at an early stage of development (eight cells) to form a single embryo that subsequently developed into a chimeric adult, exhibiting characteristics of each strain.
