Compare the Adenine DNA Nucleotide with ATP Year 12 OCR Biology A

Similarities

  • Pentose Sugar
  • Adenine Base (only true for the adenine nucleotide)
  • Phosphodiester bond between sugar and phosphate
  • An OH group on carbon 3 of the sugar
  • Phosphate group

Differences

  • ATP has two aditional phosphates
  • Deoxyribose replaced by ribose
  • An OH group on carbon 2 of the sugar/ribose

Overall comparison

TIP: Always make sure they are comparitive statements eg. ATP has ribose is not enough it should be ATP has ribose where as DNA has deoxyribose
