Which one of the following is true about DNA replication?
Which one of the following is true about DNA replication?
The lagging strand is discontinuously synthesized in the direction away from the moving replication fork.
The lagging strand is continuously synthesized in the direction away from the moving replication fork.
The leading strand is continuously synthesized in the direction away from the moving replication fork.
The leading strand is discontinuously synthesized in the direction away from the moving replication fork.
Homework Answers
The lagging strand is discontinuosly synthesized in the direction away from the moving replication fork.
It is known that that both the strands of DNA are antiparallel. At the time of replication, DNA polymerase acts continuosly on the leading strand, whereas the lagging strand moves away from the replication fork. It occurs in small, discontinuous segments, known as Okazaki fragments.

If the DNA polymerase builds both chains from the same fork, how is the second strand built if DNA polymerase only synthesizes DNA one direction (S' to 3)? The lagging strand is synthesized continuously using many short fragments, called Okazaki fragments. The leading strand is synthesized discontinuously using many short fragments, called Okazaki fragments. The lagging strand is synthesized discontinuously using many short fragments, called Okazaki fragments. The leading strand is synthesized discontinuously using many short fragments, called Okazaki fragments....

DNA Replication. Sketch a replication fork of bacterial DNA in which one strand is being replicated discontinuously and the other is being replicated continuously. List six different enzyme activities associated with the replication process, identity the function of each activity, and show where each would be located on the replication fork. In addition, identify the following features on your sketch: DNA template, RNA primer, Okazaki fragments, and single-stranded DNA binding protein.
