At the end of each replication, the complementary strand synthesized from the lagging strands would be shorter relative to the template due the lack of primer for this missing fragment. This would lead to the lack of 3' end available for the DNA polymerase. Telomerase then restores this to their original length.
In the synthesis of DNA ends by telomerase, what is the template strand, the end added, and the type of polymerase?
A. Lagging template strand, 5' end, DNA polymerase
B. Lagging template strand, 3' end, DNA polymerase
C. Leading template strand, 5' end, DNA polymerase
D. Leading template strand, 3' end, reverse transcriptase
E. Lagging template strand, 3' end, reverse transcriptase
