  2. Blockchain technology —       Digital/Cryptocurrency
  3. CRISPR – Cas9             —        Particle Physics

Which of the pairs given above is/are correctly matched?

  • 1 and 3 only
  • 2 only
  • 2 and 3 only
  • 1, 2 and 3

Answer: (b) 2 only

Notes:
  • Belle II experiment:
    • The Belle II experiment is a particle physics experiment designed to study the properties of B mesons (heavy particles containing a beauty quark) and other particles.
    • Belle II is the successor to the Belle experiment, and commissioned at the SuperKEKB accelerator complex at KEK in Tsukuba, Ibaraki prefecture, Japan.
  • ​Blockchain technology:
    • A blockchain is a digitized, decentralized, public ledger of all cryptocurrency transactions.
    • Blockchain is most simply defined as a decentralized, distributed ledger technology that records the provenance of a digital asset.
  • CRISPR-Cas9:
    • CRISPR technology is a gene-editing technology that can be used for the purpose of altering genetic expression.
    • CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) scans the genome for the right location and then uses the Cas9 protein as molecular scissors in targeted DNA.
    • The Cas9 protein is an enzyme that cuts the two strands of Double helix DNA at a specific location in the genome.
