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 ...

The spectrum of p53 mutations is not a strong argument to infer neomorphic or antimorphic mutations Unlike most other tumour suppressor genes that are inactivated by frameshift or nonsense mutations leading to disappearance or aberrant synthesis of the gene product, almost 80% of p53 gene mutations are missense mutations leading to the synthesis of a stable protein, lacking its specific DNA-binding activity and accumulating in the nucleus of tumour cells (Soussi, 2005). Whether this hig...
