Questions and Answers

What is the role of Recombination Signal Sequences (RSSs) in V(D)J recombination?

  • Bind to recombinase enzymes like RAG1 and RAG2 (correct)
  • Facilitate transcription of the gene segments
  • Directly code for the immunoglobulin gene sequence
  • Control the expression of the immune repertoire
  • Why are specific residues within the heptamer and nonamer sequences important in V(D)J recombination?

  • To initiate transcription of the gene segments
  • To regulate the immune repertoire diversity
  • To encode for the spacer regions
  • To bind to the recombinase enzyme complex (correct)
  • What is the significance of the 12/23 Rule in V(D)J recombination?

  • It determines the order of gene segments in the DNA
  • It encodes for the heptamer and nonamer sequences
  • It ensures that recombination occurs between gene segments with different spacer lengths (correct)
  • It controls the transcription process of the immune genes
  • What role do the spacer regions play in V(D)J recombination?
