Leading Strand in DNA Replication
The leading strand is the DNA strand that is replicated continuously in the 5' to 3' direction during DNA replication. This process occurs in the same direction as the movement of the replication fork, allowing for smooth and uninterrupted replication.
Explanation:
- The leading strand is synthesized by DNA polymerase in a continuous manner as the replication fork opens up.
- The enzyme DNA helicase unwinds the double-stranded DNA, exposing the template strand for replication.
- DNA primase synthesizes RNA primers on the leading strand to provide a starting point for DNA polymerase to begin replication.
- DNA polymerase then adds nucleotides in the 5' to 3' direction, following the replication fork as it moves along the template strand.
- Since the leading strand is oriented in the 3' to 5' direction, DNA polymerase can synthesize new DNA in a continuous fashion.
In contrast, the lagging strand is replicated discontinuously in short fragments called Okazaki fragments.
Therefore, during DNA replication, the leading strand refers to the strand that is replicated in the 5' to 3' direction continuously, ensuring efficient and accurate replication of the entire DNA molecule.
