DNA, RNA, & PROTEINS REVIEW
(We did this one in class)

1. Making a copy of DNA is called _________________________.

2. Which nitrogen base isn’t used during this process?

3. Name the enzyme you learned about that adds the complementary nucleotides and spell checks to make sure the new copy is correct.
