Subject-Specific FAQs

• Q: How are restriction enzymes classified based on their activity?

  A: Restriction enzymes are classified into three types:

  • Type I: Multienzyme complexes that cleave DNA randomly at distant sites.
  • Type II: Single enzyme units that recognize specific sequences and cleave nearby.
  • Type III: Require two specific sequences for cleavage, often asymmetric.
• Q: What is the role of a multiple cloning site (MCS) in a vector?

  A: An MCS is a region in a vector containing multiple restriction sites for different enzymes. It allows simultaneous insertion of DNA fragments, facilitating cloning of genes with compatible ends.
