1.The open area of DNA where replication or transcription can take place is called A. replication Bubble B. replication form c. replication strand d. replication origin 2. Once the two strands of DNA are separated, what prevents them from assuming their double- helical shape? A. Other proteins hold the strands apart B. They are too far away from each other C. Each strand has opposing charges, which keep them repelled D. All of the above
3.How does DNA polymerase move along each strand of DNA? A. Both move towards the replication fork B. Both move away from the replication fork C. One moves towards from the replication fork and the other moves away from it D. There is only one DNA polymerase on the DNA at a time
4.How can each copy of DNA at the end of replication be compared? A. Each copy is identical to each other B. Each copy is different from each other C. They are 90% similar D. They are 50% similar
