Question
In vitro DNA replication is also semi-conservative, but there are no Okazaki fragments. Why do you think that is?
Because DNA polymerase has both 3’->5’ and 5’->3’ polymerase activity in vitro.
Because there is no replication bubble in vitro.
Because no primers are needed in vitro.
Because DNA polymerase works at a higher speed in vitro.
A.Because DNA polymerase has both 3’->5’ and 5’->3’ polymerase activity in vitro.
B.Because there is no replication bubble in vitro.
C.Because no primers are needed in vitro.
D.Because DNA polymerase works at a higher speed in vitro.
Explanation / Answer
A.
Because DNA polymerase has both 3’->5’ and 5’->3’ polymerase activity in vitro.
There will be leading strand and lagging strand in normal replication,okazaki fragments are found in lagging strands,
