In one paragraph, explain the process of DNA replication!!!?

Question

I am in 10th grade biology, and i have to write a conclusion for the DNA replication process. "INCLUDE ON A PIECE OF PAPER A DESCRIPTIVE SUMMARY OF THE REPLICATION PROCESS ABOUT A PARAGRAPH LONG. BE DETAILED". This is what it says. Thanks a lot!!!!!!!!!!!!!!!

Answer 1

The DNA melts (separate from each other) into two strands progressively. These strands act like a template for nucleotides to bind, following the rule of match G with C and A with T. As the strands melt, the nucleotides are polymerized by a polymerase and new DNA is synthesised. By the end of the process, the cell presents two copies of the genetic material. This event happens only when the cell is about to divide. Good luck.

Answer 3

DNA replication or DNA synthesis is the process of copying a double-stranded DNA molecule.
Both strands in DNA run anti-parallel to each other and are complementary to one another. One of the DNA strands is built in the 5' → 3' direction, while the complementary strand is built in the 3' → 5' direction (5' and 3' each mark one end of a strand).

A DNA molecule is a long polymer built from nucelotides(Adenosine(A),Guanine(G),Cystosine(C),Thymine(T).The nucleotides which make up DNA pair with each other and form base pairs such as A::T and C:::G (two dots between A and T indicate that they are bound by two hydrogen bonds, and three dots between G and C indicate the presence of three hydrogen bonds). This means that the strand running in the 5'→ 3' direction will have base A that will pair with base T on the opposite strand running in 3'→ 5' direction.

Since DNA strands are antiparallel and complementary, each strand can serve as a template for the reproduction of the opposite strand. The template strand is preserved as a whole piece and the new strand is assembled from nucleotide triphosphates. This process is called semiconservative replication. Ideally, the two resulting strands are identical, although in reality there are always errors, though proofreading and error-checking mechanisms exist to ensure a very high level of fidelity.(In RNA, the complement of A is Uracil(U) instead of T)

Answer 4

DNA replication begins with the "unzipping" of the parent molecule as the hydrogen bonds between the base pairs are broken.
Once exposed, the sequence of bases on each of the separated strands serves as a template to guide the insertion of a complementary set of bases on the strand being synthesized.
The new strands are assembled from deoxynucleoside triphosphates.
Each incoming nucleotide is covalently linked to the "free" 3' carbon atom on the pentose (figure) as
the second and third phosphates are removed together as a molecule of pyrophosphate (PPi).
The nucleotides are assembled in the order that complements the order of bases on the strand serving as the template.
Thus each C on the template guides the insertion of a G on the new strand, each G a C, and so on.
When the process is complete, two DNA molecules have been formed identical to each other and to the parent molecule.

Answer 5

During the S phase of the cell cycle, DNA replicates. The synthesis of new DNA is a multistep process. In eurkaryotes, it involves more than 20 enzymes and other proteins. The process can be divided into three major parts:
1.binding of enzymes to existing DNA
2.unwinding of the double helix
3.synthesis of a new matching strand for each existing strand.

First enzymes and other proteins involved in DNA syntheis bind to specific regions of chromosomes called replication orogins. Each chromosome has more than one replication origin. The proteins include an enzyme that unwinds the double helix, an RNA-synthesizing enzyme, and DNA polymerase, the enzyme that catalyzes the formation of the new DNA strands.
In prokaryotes there is only one origin of replication. One is sufficient beacuse bacteria contain only one small chromosome whcih can replicate quickly. Eukarotes though have several chromosomes. These chromosomes contain much more DNA than bacteria do. Replication of a eukarotic chromosome from a single orgin would take an extremely long time.
Dna polymerase can add nucleotides only to the end of an existing nucleic acid strand. Once the DNa double helix at the origin separates an enzyme prepares each of the individual strands of DNA for synthesis of a matching strand. This enzyme synthesizes a short matchng section of RNA that acts as a primer for DNA synthesis. The base sequence of the existing DNA determines the sequence of the matching strand, whether it is RNA or DNA. For example, wherever a thymine occurs in the existing strand, an adenine is added to the new strand.
Syntheis of the new matching strand occurs continuously on only one of the original strands. This is called the leading strand. The other original stand is called the lagging strand. On the leading strand, DNa polymerase adds DNa nucleotides to the end of the RNA primer. AS the replisome moves away from the replication origin along the DNA, it unwinds more of the double helix. At the same time, DNA polymerase extends the matching strand along the leading strand. Later, another enzyme replaces the small RNA primer with DNA.
Meanwhile replication is discontinous along the lagging strand because the doulbe helix is antiparalle. but DNA polymerase can extend a primer in only one direction.
Each new double helix contains one strand of old DNa and one strand of new DNa. This type of replication is known as semiconservative replication because each of the two new double stranded DNA molecules conserves one strand of the original DNa, but adds one strand of new DNa.

This is probably too long... but very detailed...

Answer 8

DNA replicates semiconservatively. Replication of DNA is mediated by enzymes and binding proteins.
-Helicase separates antipolar strands forming a replication fork.

- Binding proteins keep strands separate and topoisomerase relieves tension and removes kinks to allow the double helix molecule to continue to unravel.

-Primase adds an RNA primer with an OH group to chemically bond with the first dNTP.

- Polymerase III (Pol I-IV) synthesizes the leading strand in the 5’—3’ direction. Antipolar lagging strand primer synthesizes RNA primer..

-Pol III elongates primer; produces Okazaki fragment

- Pol I excises RNA primer and fills the gap.. DNA Ligase links Okazaki fragments to form a continuos strand..

-DNA Polymerase III can proofread
