DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical. ... The two single strands of DNA then each serve as a template for a new stand to be created.

What advantage is it for DNA to make exact copies of itself?
DNA replication is extraordinarily accurate.
If a newly added nucleotide is not complementary to the one on the template strand, these enzymes remove the nucleotide and replace it with the correct one. With this system, a cell's DNA is copied with less than one mistake in a billion nucleotides.
What allows DNA to make a copy of itself?
DNA can replicate itself because of the way its double strands relate to one another. The purines and pyrimidines that join the two strands pair exclusively with only one other base. This ensures that when the DNA strands separate to replicate an exact copy is created.
What makes an exact copy of itself?
The process by which the DNA in a cell makes an exact copy of itself is known as DNA replication.
Why is accurate DNA replication important?
Why Does DNA Replicate? DNA replication plays an important role in the growth and renewal of cells. Growing organisms are constantly creating new cells as they develop into a larger body. ... It is very important that your DNA is replicated accurately, with new cells receiving an exact copy of your genetic sequence.
What statement about DNA replication is false?
The statement pertaining to DNA replication that is false is D: Okazaki fragments are synthesized as part of the leading strand. DNA replication...
Why is it important that both copies of the DNA molecule have the exact same sequence of nucleotides as the original DNA molecule?
Why is it important that both copies of the DNA molecule have the exact same sequence of nucleotides as the original DNA molecule? It is important that both copies of the DNA molecules have the exact same DNA allows it to be identical. ... The DNA molecule / double helix starts to separate into 2 different strands. 2.
What happens during DNA replication?
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Which statement best describes the purpose of DNA replication?
Q. Which statement BEST describes the primary function of DNA replication? To ensure daughter cells have a complete copy of DNA.
What is correct about DNA replication?
DNA replication is the process by which DNA makes a copy of itself during cell division. ... The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'. The two separated strands will act as templates for making the new strands of DNA.
When DNA makes a copy of itself the two strands unzip or separate what happens to the strands afterwards?
If the two strands of a DNA molecule are separated, each can be used as a pattern or template to produce a complementary strand. Each template and its new complement together then form a new DNA double helix, identical to the original.
What actually happens to DNA before it can be replicated copied?
Before replication can occur, the length of the DNA double helix about to be copied must be unwound. In addition, the two strands must be separated, much like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases.
What is meant by DNA copying?
DNA copying is otherwise known as DNA replication which is the process of producing 2 identical copies of DNA from one original DNA molecule during cell division. DNA copying is important because it generates variation during sexual reproduction which leads to evolution.
Where does DNA replication happen?
DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same.
Why is DNA replication semi conservative?
DNA replication: A complex process whereby the 'parent' strands of DNA in the double helix are separated, and each one is copied to produce a new (daughter) strand. This process is said to be 'semiconservative' because one strand from each parent is conserved and remains intact after replication has taken place.
Why is DNA replication essential for a cell quizlet?
Why is DNA replication essential for a cell? An organism must copy its DNA to pass genetic information to its offspring. You just studied 38 terms!
What would happen if DNA replication did not occur?
The DNA replication occurs at the synthesis phase of the cell cycle. The cell cycle is regulated at each stage. If DNA replication does not occur, then the cell cycle will not proceed to the next stage and the subsequent division will not happen. It will lead to cell death.
