69) Early in the twentieth century, many biologists believed that the genetic material of living organisms had to be made of protein–it seemed that only proteins had the complexity to store the vast amount of genetic information that organisms need. How is a relatively simple molecule such as DNA capable of storing large amounts of genetic information? Another requirement for genetic material is that it will sometimes need to be replicated. How does DNA satisfy this requirement?

 

70) Describe what happens to the two parent strands of DNA during DNA replication.

 

71) Write the sequence of the DNA strand complementary to a strand with the sequence AAATGCC.

72) Suppose you are a biologist trying to discover the process by which DNA copies itself. You grow cells in a culture that contains a special isotope of nitrogen, N-15, which will become part of any new DNA the cell makes. After one generation, you analyze the DNA and find all the DNA has some N-15 in it. You then take those cells and grow them for another generation in a culture with the normal isotope of nitrogen, N-14, and find that half of the DNA has some N-15 in it and half of it has only N-14. From this information, what can you infer is the process by which DNA replicates?
