← Life Sciences & MedicineIf a CRISPR-Cas9 system targets a gene, but off-target effects occur due to similar DNA sequences elsewhere in the genome, which adaptation minimizes these?
A)Increase Cas9 protein concentration
B)Use highly specific guide RNA sequences✓
C)Decrease overall reaction temperature
D)Add DNA polymerase to mixture
💡 Explanation
Off-target effects arise from Cas9 binding to sequences similar to the target. Using highly specific guide RNA sequences ensures that Cas9 recognizes only the intended DNA sequence, because the specificity of guide RNA determines the binding location rather than altered protein levels or reaction conditions.
