- Label the double helix molecule: Nitrogen Base Pair (between complementary bases), Sugar/Phosphate Backbone (along the sides of the helix).
- Color the original strands: Draw a thick BLUE line over each helix strand to represent the original strands.
- Label the unwound DNA molecule: Deoxyribose Sugar (on the backbone), Phosphate (on the backbone), The “Missing” Bases (the empty boxes on the right side).
- Color the unwound DNA: Sugars – ORANGE, A’s – GREEN, T’s – PINK, C’s – RED, G’s – PURPLE.
- Label the unzipped DNA molecule: The “Missing” Bases (empty boxes on both sides), DNA Helicase (the cloud-like shape breaking the bonds).
- Color the unzipped DNA: Sugars – ORANGE, A’s – GREEN, T’s – PINK, C’s – RED, G’s – PURPLE.
- Label the replicating DNA: The “Newly Added” Bases (filled boxes on the right side), DNA Polymerase (2x) (the two oval shapes where new bases are being added).
- Color the replicating DNA: All original bases BLUE, All newly added bases YELLOW.
- Color the replicated DNA: Original Backbone BLUE, New Backbone YELLOW.
Parent Tip: Review the logic above to help your child master the concept of dna replication worksheet.
