Questions and Answers

What is one of the functions of lncRNAs mentioned in the text?

  • Forming triplex structures with single-stranded DNA
  • Binding small ligands
  • Undergoing translation into proteins
  • Interacting with miRNA in RISC complexes (correct)

    • Why are lncRNAs considered as potential therapeutic targets according to the text?

  • For their involvement in DNA replication
  • Due to their role in protein synthesis
  • Because they regulate gene expression (correct)
  • Based on their function in cell metabolism

    • What does Xist (X inactive specific transcript) primarily contribute to in mammalian female cells?

  • Protein translation
  • DNA replication
  • Cell division
  • Regulation of X-chromosome inactivation (correct)
