Multiple Choice

Figure 13.1
- Figure 13.2
In an experiment, DNA is allowed to replicate in an environment with all necessary enzymes, dATP, dCTP, dGTP, and radioactively labeled dTTP (3H thymidine) . After several minutes, the DNA is switched to nonradioactive medium and is then viewed by electron microscopy and autoradiography. Figure 13.2 represents the results. It shows a replication bubble, and the dots represent radioactive material. Which of the following is the most likely interpretation of the results?

• A) There are two replication forks going in opposite directions.
• B) Thymidine is being added only where the DNA strands are farthest apart.
• C) Thymidine is being added only at the very beginning of replication.
• D) Replication proceeds in one direction only.
