DNA Structure
Which two bases belong to the purine group?
Which two bases belong to the pyrimidine group?
Write the letter code of your chain on your paper and on the white board.
Probably each chain is unique. Explain why.
What purine-pyrimidine pairs can you form?
Compare the positions of the new nucleotides with the positions of the original ones.
B.
C.
DNA Replication
