The direction of DNA replication on the leading strand occurs in the?

The enzyme DNA polymerase synthesises strands in the 5 prime to 3 prime direction, and as DNA is antiparallel the replication of the leading strand occurs from the 3 prime end of the template to the 5 prime end of the template.

Compare the leading and lagging strands during replication?
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
There is a y shaped replication fork on each side of each replication bubble what are the sides of the replication fork called?
One is known as the Leading strand, and the other is known as the Lagging strand.
What is the DNA strand that is synthesized continuously during DNA replication?
leading strand
At each replication fork one new strand of DNA is made of many small pieces. what is the strand of DNA called?
When the two parent strands of DNA are separated to begin replication, one strand is oriented in the 5' to 3' direction while the other strand is oriented in the 3' to 5' direction. DNA replication, however, is inflexible: the enzyme that carries out the replication, DNA polymerase, only functions in the 5' to 3' direction. This characteristic of DNA polymerase means that the daughter strands synthesize through different methods, one adding nucleotides one by one in the direction of the replication fork, the other able to add nucleotides only in chunks. The first strand, which replicates nucleotides one by one is called the leading strand; the other strand, which replicates in chunks, is called the lagging strand. The lagging strand replicates in small segments, called Okazaki fragments. These fragments are stretches of 100 to 200 nucleotides in humans (1000 to 2000 in bacteria).
Is DNA replication bidirectional in prokaryotes?
Because in eukaryote the DNA is antiparallel, so the polymerase has to go in one direction up the leading strand and in the reverse direction down the lagging strand. Of course, two polymerase at the same time.
Is RNA polymerase used in both leading and lagging strands of DNA replication?
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
Are the leading strand and lagging strand of DNA replication copied in the same direction?
No, both will be synthesized in opposite directions
Compare the leading and lagging strands during replication?
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
What are leading strands?
Leading strands are one of the two newly synthesized DNA strands during DNA replication. They are synthesized in a continuous manner in the 5' to 3' direction, following the replication fork. The leading strand is synthesized in the same direction as the replication fork is moving, allowing for continuous synthesis.
There is a y shaped replication fork on each side of each replication bubble what are the sides of the replication fork called?
One is known as the Leading strand, and the other is known as the Lagging strand.
Which is true about the elongation of the leading strand during DNA synthesis?
progresses away from the replication fork.
What is the DNA strand that is synthesized continuously during DNA replication?
leading strand
What is the name of the strand that replicates in a direction toward the replication fork?
Lagging strand.
Does dna ligase help assemble the leading strand?
Not in general replication as the leading strand is replicated straight away. The lagging strand is replicated in pieces that need ligase to affix them, one to the other. However, in a replication bubble, when a lagging strand runs into a leading strand, and later the primers are replaced, ligase is still needed. Therefore, technically, the leading strand does need the ligase once.

Why is replication on one strand of DNA continuous while on the other strand the replication must be discontinuous?
New strands of DNA can only be created in one direction - 5' to 3'. This is because only the 3' end of the DNA is able to join to a new nucleotide. The two strands of DNA are antiparallel - meaning they run in different directions. Therefore only one strand (called the leading strand) is running in the correct direction for continuous replication. The other strand (called the lagging strand) must first be looped around so that small sections can be replicated in the correct direction.
