DNA-Biology.
Name the four types of nitrogen-containing bases found in DNA Which bases are complementary to one another? How are they held together in the double helix of DNA? Describe the structure of DNA. Where are the bases, sugars, and phosphates in the structure? Describe the process of DNA replication. How do mutations occur? Describe the principal types of mutations. Re-read “Scientific Inquiry: The discovery of the Double Helix” on page 208. As you learned in this reading, scientists in different laboratories often compete with one another to make new discoveries. Do you think this competition helps promote scientific discoveries? Sometimes researchers in different laboratories collaborate with one another. What advantages does collaboration offer over competition? What factors might provide barriers to collaboration and lead to competition? Extras ordered: none
