Why is it important that exact copies of DNA are produced during replication How is DNA replication related to cancer?

producing exact copies ensures that when a cell divides, the offspring cells will receive the same genetic information as the parent cell. how is DNA replication related to cancer? cancer can result when errors in the replication of DNA in genes that control how a cell divides.

Why is it important for both copies of the DNA molecule to 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.

Why is it important that an exact copy of DNA be made before mitosis?

DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

Why is it important for DNA to be replicated exactly before a cell divides quizlet?

Cell replication is necessary before cell division so that the daughter cells have the correct number of chromosomes. Cell division must occur for growth, repair, and reproduction. The double helix / DNA is unravelled so that the two strands are seperated. This exposes (the now unpaired) bases.

Why is it important that the 2 molecules of DNA are identical consider what happens to the DNA after it is replicated?

Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner. … Each template and its new complement together then form a new DNA double helix, identical to the original.

Why is it important that two strands of DNA are identical?

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.

Why is it necessary for the cell to grow and replicate its DNA before the start of meiosis?

DNA replicates before a cell divides to give a complete set of genetic instructions to each daughter cell. If a cell begins meiosis without duplicating its DNA, the two resulting cells would have insufficient DNA to develop properly, as there would only be one copy of each chromosome in the parent cell.

Why is it important that the copies of DNA that are given to new daughter cells be exact copies of the original?

Replicating before the cell divides makes sure the organism has its own copy of the original DNA. This copy will be exactly the same as the parent cell. This is important as it will allow the new cells to function correctly according to the genetic information stored.

Why is DNA replication necessary in a cell Why must it be very accurate quizlet?

Why is DNA replication necessary in a cell? Why must it be very accurate? Because a cell contains only one copy of its DNA “program,” it must make another copy before it divides so that each cell can have a copy.

What is the significance of this molecule being able to replicate itself?

Molecules that can make copies of themselves are thought to be crucial to understanding this process as they provide the basis for heritability, a critical characteristic of living systems. New findings could inform biochemical questions about how life began.

What is the importance of DNA replication quizlet?

The sole purpose of DNA replication is to generate identical DNA molecules, as they are the blueprint that makes life possible.

Why must DNA be replicated quizlet?

DNA must be replicated in order to form identical daughter cells. If DNA replication allows for four chromosomes, then it can split into two cells with two chromosomes each. … Helicase unzips and unwinds the DNA double helix by breaking hydrogen bonds.

What is the importance of DNA replication to all living organisms quizlet?

The purpose of DNA replication is to produce two identical copies of a DNA molecule. This is essential for cell division during growth or repair of damaged tissues. DNA replication ensures that each new cell receives its own copy of the DNA.

Why is it important that the newly created DNA is identical?

Yes, your DNA needs to copy itself every time a new cell is created. The new cell needs to have DNA exactly like the rest of your cells. Otherwise, that cell might malfunction. That’s why it’s important that the process of copying DNA, called DNA replication, is very accurate.

When DNA replicates two identical copies of DNA molecules are produced which are?

semiconservative replication

This is known as semiconservative replication. When two DNA copies are formed, they have an identical sequence of nucleotide bases and are divided equally into two daughter cells.

What happens during copying of DNA?

Answer: A method where a molecule of DNA creates two identical copies of itself inside a reproductive cell is called copying of DNA. In the process of DNA replication, the DNA makes multiple copies of itself. It is a biological polymerization which proceeds in the sequence of initiation, elongation, and termination.

What would happen if the DNA strands were not copied correctly?

When replication mistakes are not corrected, they may result in mutations, which sometimes can have serious consequences. Point mutations, one base substituted for another, can be silent (no effect) or may have effects ranging from mild to severe.

How do cells make accurate copies of DNA?

When a cell divides, it replicates its DNA by splitting apart double-stranded DNA and makes new copies along the single strands of the original DNA. … By always keeping the original DNA strands, it ensures that it maintains the original information.

Why is understanding the structure of DNA and how it is replicated important?

Because, by comprehending how DNA is formed help us know how it is replicated, translated and transcribed. and by knowing how DNA replicates, we can know how it is formed. both of this concepts go hand in hand, allowing us to further identify errors in transcription, or how coding for proteins work.

Why is it important for cells to grow before cell division?

It is important for cells to divide so you can grow and so your cuts heal. It is also important for cells to stop dividing at the right time. If a cell can not stop dividing when it is supposed to stop, this can lead to a disease called cancer. Some cells, like skin cells, are constantly dividing.

Why is it necessary for a cell to grow?

As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only form of reproduction. In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells.

What would happen if a cell is unable to replicate its DNA?

The cell’s DNA is copied during the synthesis phase. … If the cell has not properly copied its chromosomes, an enzyme called cyclin dependent kinase, or CDK, will not activate the cyclin, and the cell cycle will not proceed to the next phase. The cell will undergo cell death.

Why is it necessary for the cell to grow and duplicate its DNA before the start of meiosis quizlet?

It is necessary for cells to grow and duplicate the DNA before the start of meiosis because that way the daughter cells get a full equal set of DNA. How do the chromosomes separate in anaphase I? They separate is anaphase 1 because they are pulled apart by the centrosome so that the sister chromatids are separated.

How does this process of DNA replication ensure exact copies are made?

Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner. … Each template and its new complement together then form a new DNA double helix, identical to the original.

Why does the DNA replicate prior to cell division?

Why is it important that DNA replication take place before cell division? … In order for all of the cells in your body to maintain a full genome, each cell must replicate its DNA before it divides so that a full genome can be allotted to each of its offspring cells.

What is the importance of DNA replication in S phase?

The most important event occurring in S phase is the replication of DNA. The aim of this process is to produce double the amount of DNA, providing the basis for the chromosome sets of the daughter cells.

What actually happens to DNA is necessary before or as it is 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 features of DNA enable it to be replicated?

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 is the purpose of DNA replication and when does it happen?

The purpose of DNA replication is to produce two identical copies of a DNA molecule. This is essential for cell division during growth or repair of damaged tissues. DNA replication ensures that each new cell receives its own copy of the DNA.

What is the significance of DNA replication during the S phase of the cell cycle quizlet?

Replicating organelles. the synthesis phase (S) of its life. During this time the DNA within the nucleus is replicated to create 2 full copies of the genome. This is so that when the cell divides, each cell will gain 1 copy of the genome each.

What should happen to a cell before DNA can be replicated quizlet?

DNA replicates before a cell divides so that each daughter cell receives a complete set of genetic information. -If a cell does not successfully pass a checkpoint, the cell cycle may stop, or the cell may enter apoptosis and die. … Are all of the chromosomes split in half so that each new cell gets a full copy?

Why is replication important to the growth and development of a multi cellular organism?

DNA replication is important since it creates a next copy of DNA that have to go into one of the two daughter cells when a cell divides. Without replication, each cell lacks adequate hereditary fabric to give instructions for creating proteins vital for bodily purpose.
