Question
In DNA replication, continuously synthesis occurs on the leading strandMultiple choice question.without RNA primers.toward the origin of replication.in the 5' to 3' direction.and creates Okazaki fragments.
Solution
The correct answer is "in the 5' to 3' direction."
Here's why:
-
DNA replication is always carried out in the 5' to 3' direction. This is due to the structure of the nucleotides and the enzymes involved in the process.
-
The leading strand is synthesized continuously, which means it is replicated in the same direction as the replication fork is moving.
-
RNA primers are needed to start the replication process, so the statement "without RNA primers" is incorrect.
-
The replication does not move toward the origin of replication, but rather away from it.
-
Okazaki fragments are created on the lagging strand, not the leading strand, during DNA replication. The lagging strand is synthesized discontinuously in short segments, which are later joined together to form a continuous strand.

Why is the lagging strand synthesised in Okazaki fragments? Group of answer choicesBecause it is synthesised towards the replication forkBecause DNA polymerase III can only synthesise short fragmentsBecause it is synthesised by DNA polymerase I, which can only do short regions Because it is synthesised away from the replication fork
