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.
Why do enzymes work in opposite detections in replication?
In DNA replication, enzymes (DNA polymerases) work in the 3 prime to 5 prime end, creating the new strand in the 5 prime to 3 prime direction. This is due to their structure- they add bases to preexisting 3 prime anchors. Of the five carbons on the deoxyribose, the 3 prime is joined to a hydroxyl and the 5 prime is joined to a phosphate group.
How many rounds of chromosome replication occur in the cell?
how many rounds of chromosome replication occur i the cell pirior to mitosis
Flow chart of 8 steps of DNA replication?
The eight steps of DNA replication are: 1. DNA strands separate, 2. formation of replication fork, 3. RNA primase binds, 4. bases pair up, 5. elongation, 6. RNA primers removed, 7.termination, 8. repair. this can occur in any cell.
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).
Why does DNA replication have to be in an anti-parallel direction?
DNA polymerase III can only work in the 5' to 3' direction.
What direction can DNA synthesis occur?
3'->5'
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.
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.
What is birectional replication in DNA?
A DNA molecule has two complementary strands, the top (leading) one is 5' to 3' and the bottom (lagging) one is 3' to 5'. The 5' carbon has a phosphate group linked to it and the 3' carbon has a hydroxyl group. During replication, both strands get replicated however DNA strands due to their molecular structure can only be replicated from 5' to 3' so the lagging strand is replicated in 5' to 3' pieces called Okazaki fragments. However, even with this, replication still happens in both strands, even if in the same direction (5' to 3').
Why do enzymes work in opposite detections in replication?
In DNA replication, enzymes (DNA polymerases) work in the 3 prime to 5 prime end, creating the new strand in the 5 prime to 3 prime direction.

When DNA replicates what are the new DNA made of?
its made of DNA. Replication just doubles the DNA, just like when bacteria or humans replicate.. the new human is .. well made of human.... It is opposite and anti-parallel.... 5-AATGTC-3 Original strand 3-TTACAG-5 new strand Each new molecule will have 1 original strand, and 1 daughter/newly synthesized strand. DNA replication results in DNA DNA transcription results in a strand of RNA
Which is true about the elongation of the leading strand during DNA synthesis?
progresses away from the replication fork.

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.
