Question
Indicate whether the following statements are true or false. If a statement is false, explain why it is false. 19. 20. 21. Primase is needed to initiate DNA replication on both the leading strand and the lagging strand. The sliding clamp is loaded once on each DNA strand, where it remains associated until replication is complete. Telomerase is a DNA polymerase that carries its own RNA molecule to use as a primer at the end of the lagging strand. Primase requires a proofreading function that ensures there are no errors in the RNA primers used for DNA replication. 22.Explanation / Answer
19) true
20) false
Sliding camp is loaded only once on the leading starnd
Lagging strand requires reloading again during synthesis of new primer
21)true
22)false
Primase does not have proof reading function and neither it needs one as the RNA primers are not permanent. They will be removed and replaced by DNA polymerase
