Sample interview questions: Can you discuss any experience you have with CRISPR-based gene activation or repression techniques in biotechnology research?

Sample answer:

  • CRISPR-based gene activation:

    • Experience in utilizing CRISPRa (CRISPR activation) systems for targeted gene overexpression.
    • Proficient in designing sgRNAs (single-guide RNAs) to specifically target the promoters or regulatory regions of genes of interest.
    • Hands-on experience with various CRISPRa platforms, including dCas9-VP64, dCas9-SunTag, and CRISPRi-dCas9-KRAB.
    • Ability to optimize CRISPRa conditions, such as sgRNA concentration, transfection methods, and cell type selection, to achieve efficient gene activation.
    • Expertise in evaluating gene activation efficiency through quantitative gene expression analysis methods, such as RT-qPCR, RNA-seq, and single-cell RNA-seq.
  • CRISPR-based gene repression:

    • Experience in employing CRISPRi (CRISPR interference) systems for targeted gene silencing.
    • Proficient in designing sgRNAs to specifically target the coding regions or regulatory elements of genes of interest.
    • Hands-on experience with various CRISPRi platforms, including dCas9-KRAB, dCas9-MS2, and CRISPRi-dCas9-SID.
    • Ability to optimize CRISPRi conditions, such as sgRNA concentration, transfection methods, and cell type selection, to achieve efficient gene repression. Read full answer
