An a-t base pair is stabilized by only two hydrogen bonds. hydrogen-bonding schemes of very similar strengths can also be drawn between other base combinations that normally do not occur in dna molecules, such as the a-c and the a-g pairs. what would happen if these pairs formed during dna replication and the inappropriate bases were incorporated? discuss why this does not often happen.

Step 1 review the imaginary strand of dna below. note the complementary base pairs. a g c a a t c c g t c t t g g t c g t t a g g c a g a a c c 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.
