DNA Replication Illustrations: A step-by-step guide to DNA replication during the S phase of Interphase, including labeling and coloring instructions for visual learning.

- Label the double helix: Nitrogen Base Pair (between complementary bases), Sugar/Phosphate Backbone (the outer strands of the helix).
- Color the original strands: Draw a thick BLUE line over each helix strand.
- In the unwound molecule, label: Deoxyribose Sugar (pentagon shapes on backbone), Phosphate (circles on backbone), The “Missing” Bases (empty boxes opposite existing bases).
- Color in unwound molecule: Sugars – ORANGE, A’s – GREEN, T’s – PINK, C’s – RED, G’s – PURPLE.
- In the unzipped molecule, label: The “Missing” Bases (empty boxes), DNA Helicase (cloud-like shape between strands).
- Color in unzipped molecule: Sugars – ORANGE, A’s – GREEN, T’s – PINK, C’s – RED, G’s – PURPLE.
- In replicating DNA, label: The “Newly Added” Bases (bases filled in opposite template), DNA Polymerase (2x) (two oval shapes near new bases).
- Color in replicating DNA: All original bases BLUE, All newly added bases YELLOW.
- In replicated DNA, color: Original Backbone BLUE, New Backbone YELLOW.
