Questions and Answers

What is the role of snRNPs in splicing?

  • They stabilize mRNA
  • They degrade introns
  • They form a spliceosome (correct)
  • They bind to exons

    • What is the consequence of homozygous mutations in the 5' or 3' intronic splice site?

  • mRNA is translated incorrectly
  • mRNA cannot leave the nucleus and is degraded (correct)
  • mRNA can leave the nucleus but is degraded
  • mRNA is translated normally

    • What type of bond is formed between the branch site A and the splice donor site of the intron during splicing?

  • 3'-->5' phosphodiester bond
  • 2'-->5' phosphodiester bond (correct)
  • 5'-->3' phosphodiester bond
  • 5'-->5' phosphodiester bond
