Objective

Build nucleosides and nucleotides from their respective components, and understand the chemical differences between DNA and RNA nucleotides.

Reward

Collect the Nucleotide Structure token and unlock the DNA/RNA Structure simulation marker.

Drag and drop the falling molecules onto the pentose sugars below to construct nucleosides. Build four different DNA nucleosides and four different RNA nucleosides.
Great! You’ve created DNA and RNA nucleosides. Now drag and drop the falling molecules onto the nucleosides to construct DNA and RNA 5’ monophosphate nucleotides.
Nice work! Now sort the nucleotides: drag and drop the DNA nucleotides into the left box and the RNA nucleotides into the right box.
Congratulations, you finished the exercise! However, your score indicates you have some uncertainty with deoxyribonucleotide and ribonucleotide structure. Try the exercise again to collect the Nucleotide Structure token and unlock the marker for the DNA/RNA Structure simulation.
Congratulations, you finished the exercise! However, your score indicates your knowledge of deoxyribonucleotide and ribonucleotide structure is not adequate. Consider reviewing your text, and then try the exercise again to collect the Nucleotide Structure token and unlock the marker for the DNA/RNA Structure simulation.
