STEP 1 Review the imaginary strand of DNA below. Note the complementary base pairs. AGCAATCCGTCTTGG
TCGTTAGGCAGAACC

STEP 2 To begin replicating this strand of DNA, draw the two sides of the strand separating.

STEP 3 Now, draw the free-floating bases linking up with the separate sides. Remember to
follow the rules of complementary base pairing.

STEP 4 Draw the two resulting DNA strands.
