QUIZ 3 Correct Answer--------- Which of the following statements are FALSE? Mark all that apply. 1. A knockout mouse is constructed by injecting a sample of recombinant DNA into a fertilized mouse embryo. Injected DNA is then randomly incorporated into the mouse's genome. 2. miRNAs hybridize perfectly with target mRNAs. 3. In RNAi, if a perfectly complementary 21-nt mRNA is found, Dicer will cleave the mRNA, which knocks down target gene expression. 4. Diploid yeast cells can be ...
