Why is DNA important?

• It teleports cookies to my locker.

• It carries the instructions for our cells.

• It allows me to be invisible.

• It gave us a snow day in August.

What does the structure of DNA resemble?

• an airplane propeller

How does DNA replicate? Choose the 3 steps.

• 1st, it unwinds and unzips.

• Finally, Elves weave new bases onto the old DNA.

• Then, new bases match up to the parent strands.

• Next, the two single stands act as a template for the new strand to be created.

Why is DNA replication and example of semi-conservative replication?

• Each new stand of DNA has all new material.

• The DNA happens to just duplicate each base pair.

• Part of the original DNA is used to create each of the new DNA strands.

• The phosphate groups are no longer attached to the 5 carbon sugar or the leg bone.
