Nucleotide structure and bonds holding them

Cards (4)

  • DNA has two antiparallel chains held together by hydrogen bonds between complementary bases (A-T & C-G)
  • Phosphate groups are negatively charged so they repel one another, this causes DNA strands to be stiff and straight.
  • The phosphodiester bond is the link between nucleosides to form polynucleotides
  • RNA is single stranded
