View the animated interactive tutorial pages of DNA structure A, B, C & D. Use the mouse (click and drag) to move the DNA molecule around.
1) In tutorial A, how are the hydrogen bonds between the base pairs of the DNA indicated? (two word answer)
2) In tutorial B, how many C-G base pairs are found in the DNA molecule? How many A-T base pairs?
3) In tutorial B click “Replicate.” At what end of the DNA molecule does replication begin–5′ or 3′ (read: “5 prime or 3 prime)?
4) The first three bases reading from the 3′ (read: “3 prime”) end of either strand of the DNA molecule are GCC. What would these bases be transcribed into if making a piece of mRNA from this DNA?
5) In tutorial C, erase the bases and the H (hydrogen) bonds. (See light blue box at the bottom of the tutorial.) You are left with the phosphates and the sugars. These make up what is known as the _______ of the DNA molecule. (Fill in the blank.) Can you see the double helix? What architectural structure does it remind you of?
6) The two strands in a DNA helix exhibit complementary base pairing. What is complementary base pairing?
