Q

RNA structure

  • Primary structure: ________________
  • Secondary structure: complementary regions within a strand base pair to each other “____” or “_____”
  • Tertiary structure: more _______ of RNA complement base pair
  • Quaternary structure: RNA strands interact
A

RNA structure

  • Primary structure: sequence of nucleotides if ones strand is known complement is also known
  • Secondary structure: complementary regions within a strand base pair to each other “hairpin” or “stem-loop”
  • Tertiary structure: more distant regions of RNA complement base pair
  • Quaternary structure: RNA strands interact
