DNA polymerase is instrumental in DNA elongation as it catalyzes the addition of deoxyribonucleoside triphosphates to the 3 prime end hydroxyl group of the DNA chain. DNA polymerase binds on the origin of replication, and forms a pre-replication complex with other proteins. The replication complex unwinds DNA during replication

What Replicates DNA by making a complementary copy of the original?
DNA replicates itself. What happens is, with the help of enzymes, the nitrogenous bases of DNA break away from each other, then copy themselves and re-attach. This process forms 2 strands of identical DNA.
Difference between DNA replication and transcription?
1. Replication is the duplication of two-strands of DNA. Transcription is the formation of single, identical RNA from the two-stranded DNA. 2. There are different proteins involved in replication and transcription. 3. In replication, the end result is two daughter cells, while in transcription, the end result is a protein molecule. 4. In transcription, DNA serves as the template for RNA synthesis.
What is the strand of DNA that forms during replication 5' GGTTTCTTCAAGAGA '3?
The strand of DNA that forms during replication complementary to the sequence 5' GGTTTCTTCAAGAGA 3' is 3' CCAAGAACTTCTCTC 5'. During DNA replication, the new strand is synthesized in the 5' to 3' direction, pairing adenine with thymine and cytosine with guanine. Therefore, the complementary strand would be built from the corresponding bases of the original strand.
What type of DNA molecule forms as a result o DNA replication?
During DNA replication the two strands of the DNA helix split apart and the ribosome reads off the template strand producing an exact copy of this strand. Then RNA polymerase base pairs both of the strands, producing 2 semi-conservative strands.
Which structure forms as DNA unwind?
A replication bubble.
Two new strands of DNA molecules grow as bases are added by the enzyme?
DNA polymerase during DNA replication. Each new strand is complementary to the original template strand and forms a double helix structure.

Why DNA replication is popularly known as enzyme dependent?
DNA replication is aided by enzymes. Without the enzymes DNA will not be able to replicate.There are three main enzymes involved-Helicase - This enzyme separates the two parental DNADNA Polymerase - This enzyme exists in different forms and each one of them have a specific function in the replication of DNA.In short, it enhances each strands, adds base pairs and repairs any damage done to the strands during the replication process.Ligase - This enzyme puts the two stands together after the replication is complete.

What are the short segments produced in the formation of the 3'-5' strand of DNA called?
During DNA replication, the lagging strand is replicated ~1000 (E. coli) base pairs at a time, forming numerous "Okazaki fragments".Okazaki fragments form because polymerase is only able to replicate DNA in one direction, but DNA is double stranded, with the strands running anti parallel (in opposite directions). The polymerase waits for a region of DNA to be unwound, and while the leading strand is replicated continuously, on the lagging strand the polymerase waits until a region of single stranded DNA is produced before replicating it. This discontinous replication forms the Okazaki fragments, which can then be joined together by ligase (although a different polymerase enzyme, pol I in E. coli, is needed as well to replace the RNA primers with DNA).
How does DNA replication differ in prokaryotes and eukaryotes?
1. In eukaryotic cells replication forks make several start sites along the DNA strand which forms replication "bubbles" which get larger the more DNA is copied, and stop when DNA replication is complete. In prokaryotic cell's DNA is formed in a loop, two replication forks start along one part of the loop (origin replication) and the replication forks copy DNA in opposite directions until they meet at the other side of the loop, making an exact copy of DNA.
What type of DNA molecule forms as a result o DNA replication?

Which structure forms as DNA unwind?
A replication bubble.
What is the replication bubble?
A replication bubble is a region in DNA where the double helix unwinds and separates during the process of DNA replication. It forms at the origin of replication, where two replication forks move outward in both directions, allowing for the synthesis of new complementary strands. This structure enables simultaneous replication of both strands of the DNA, ensuring efficient duplication of the genetic material. The size and number of replication bubbles can vary depending on the organism and the specific DNA being replicated.
What I replication bubble?
A replication bubble is a region in DNA where the double helix is unwound and separated during the process of DNA replication. It forms as the replication machinery moves along the DNA, creating two single-stranded templates for new complementary strands to be synthesized. The bubble expands as replication progresses, and multiple replication bubbles can exist simultaneously on a single DNA molecule to expedite the replication process. This mechanism is essential for accurately duplicating genetic information before cell division.
What happens at the DNA replication fork?
The DNA replication fork is where the replication origin forms the Y shape. The replication fork moves down the DNA strand to the strand's end, resulting in every replication fork having a twin.
