Question
The strand that is synthesized in the 5’ to 3’ direction.
Group of answer choices
- both leading and lagging strand
- lagging strand
- leading strand
- Next
Solution
The strand that is synthesized in the 5’ to 3’ direction is the leading strand.
Here's why:
-
DNA replication always occurs in the 5' to 3' direction. This is because new nucleotides are added to the 3' end of the newly-forming strand.
-
The leading strand is synthesized continuously in the 5' to 3' direction. This is because it is oriented in the same direction as the replication fork is moving.
-
On the other hand, the lagging strand is synthesized discontinuously in short segments known as Okazaki fragments. This is because it is oriented in the opposite direction to the replication fork.
So, the correct answer is the
