You would like to create a mouse model of the human disease Huntington's chorea, a dominant disease caused by a
gain of function mutation in the human HD gene. Which of the following strategies would be suitable? Select all that
apply
Use CRISPR-Cas9 to introduce frameshift mutations in the mouse HD gene; breed the resulting mutant
mice to generate homozygous mutants
Introduce the wild type human HD allele as a transgene into mouse genome; select transgenics where
human HD replaced the wild type mouse HD gene via homologous recombination
Introduce the mutant human HD allele as a transgene into the mouse genome with transgene integration
anywhere in the mouse genome
Use CRISPR-Cas9 technology to cut the mouse HD gene; supply the mutant human HD allele as a repair
template and select for transgenics where the the mutant human HD replaced the mouse HD gene

Part of the wild type sequence in a gene is AGGATCTTGGAC
If this sequence is targeted by a guide RNA for Cas9 cleavage between the two adjacent T's, and no repair template is
provided, which of the following alleles is expected to arise from NHEJ repair of the broken sequence? Select all that
are in the range of expected outcomes for NHEJ repair.
