no DNA replicates before mitosis. It replicates in the S phase of inter phase

How is DNA replicated?

In a cell, DNA replication must happen before cell division can occur. DNA synthesis begins at specific locations in the genome, called "origins", where the two strands of DNA are separated. RNA primers attach to single stranded DNA and DNA polymerase extends from the primers to form new strands of (MORE)

How does DNA replicate?

\n \n\n \n\n \nunwinding: the old stands that make up the parent molecule are unwound or unzipped. a special enzyme called helicase unwinds the molecule.complementary base pairing:new complimentary nucleotides(A to T, and C to G) are positioned by base pairing. joining:the complimentary nucleotides (MORE)

How DNA is replicated?

The first step in DNA replication is the binding of DNA helicase, which unwinds the double helix of DNA. Single-stranded binding proteins attach to the separated strands to hold them apart. DNA gyrase, a type of topoisomerase, binds further down the strands. Gyrase breaks, twists, and rejoins the DN (MORE)

Why does DNA replicate?

DNA molecules undergo replication during interphase of the cell cycle. In this way, each newly formed cell receives a copy of the pre-existing cell's genetic information so that the new cell can synthesize the proteins necessary to maintain life functions, build and repair cell parts, and pe (MORE)

How DNA replicate?

DNA first unwinds by the polymerase into two strands, then polymerases run over the two strands, replace a new strand on each old strand, forming two new DNA with one new strand and one original strand in each. (The polymerase is the enzyme)

Why is DNA replication important to mitosis?

Because with mitosis, you are copying the original organism exactly. Meaning you can't take cells directly from the original without losing cells or DNA. By replicating them, they are copying the original without compromising it. It's spelled LOSE not LOOSE

When does DNA replication occur in Mitosis?

In Mitosis, DNA replication begins in stage 3 after the DNA has grown, it begins to split. It then splits and replicates into two cells, where it continues to replicate.

Why does DNA replication occur before mitosis begins?

DNA has to replicate before mitosis to keep the number of chromosomes and DNA in the cell consistent. Mitosis is the process of reproducing cells by splitting one cell in half to make two. If the DNA didn't replicate, the two daughter cells wouldn't be able to have a complete strand. DNA replicates (MORE)

Why does DNA have to be replicated?

\nAll cells need a copy of the DNA in order to work and function properly, and if DNA wasn't replicated, all of the cells would have to keep going back to the brain for instructions on what to do next, and the veins to the brain would clog, and the person would die.

What replicates DNA?

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.

What might happen if DNA replication and mitosis were not highly controlled?

Activites within the cell cycle are monitered and controlled at specific stages, or checkpoints. Checkpoints in the life of a cell are like checkpoints during a mountain bike race. Officials monitor racers to ensure that competitors have enough water and food and that no one is hurt. If an official (MORE)

Can DNA replication be called mitosis?

DNA replication is technically not part of mitosis. Mitosis is simply the splitting of the nucleus. DNA replication however is part of the interphase, which is part of the cell cycle. The DNA replication is also known as the S phase in the interphase. In this part, the DNA is replicated creating two (MORE)

When does replication occur in the replication of DNA?

In Mitosis - the events that prepare the Eukaryotic Cell for division and the division process itself constitute a complex cell cycle. Interphase is the 1st phase of the cycle and is made-up of 3 phases (G1, S, & G2). It is during the S-phase (the "Synthesis" Phase), that the DNA replicates, produci (MORE)

What is DNA replicating?

DNA replication , the basis for biological inheritance, is a fundamental process occurring in all living organisms to copy their DNA. This process is "semiconservative" in that each strand of the original double-stranded DNA molecule serves as template for the reproduction of the complementary stran (MORE)

Why must the DNA replicate before mitosis?

Two daughter cells that are genetically identical are formed during the process of mitosis. DNA hence needs to be replicated so that there are two copies of each chromosome for each daughter cell.

Why must DNA replicate before mitosis starts?

Mitosis is asexual reproduction. DNA replication occurs in the S phase of Interphase and this is necessary for the production of the two new Daughter Cells. A human skill cell has 46 chromosomes. The cell is a parent cell. After Mitosis ends, then each Daughter Cell will still have 46 chromosomes (MORE)

How is mitosis and the cell cycle related to DNA and DNA replication?

mitosis this is the type of cell division which take place during growth and development of a living organism prominent in asexual living organism which does not require for cell division of gamete cells with stages and comes into relationship with DNA replication by multiple division of it's cells. (MORE)

What is DNA transcription and DNA replication?

DNA transcription is the process of copying a DNA template onto a messenger RNA. This mRNA is then translated into an amino acid sequence (polypeptide/protein). DNA replication is the copying of DNA to make more copies of DNA.

Is it true that DNA replication can also be called mitosis?

No, mitosis is the replication of a cell. There are specific phases of mitosis which can be associated with specific stages of cell replication. During Interphase and early Prophase, the cell unwinds its DNA and begins to replicate it.

What does the DNA replicate?

DNA replication replicates the DNA. It results in two identical copies of DNA in preparation for the process of mitosis.

What is replicated during DNA replication?

During DNA replication, all your chromosomes produce a duplicate copy of themselves with identical genetic information. This is so that when they divide, in the case of mitosis, each daughter cell will have the exact same genetic information as the parent cell.

Why is DNA replication required prior to mitosis?

Because mitosis produces 2 genetically identical cells, each cell must have an equal amount of DNA as the parent cell had. Because of this, the DNA makes a duplicate copy of itself before mitosis begins, so that when the chromosomes separate each cell that forms will have as much DNA as the parent c (MORE)

Why DNA be replicated before mitosis and meiosis?

Because mitosis must create an exact copy of the cells, the DNA is duplicated. For meiosis, the resulting diploid zygote (offspring of two gametes) contains 46 chromosomes before becoming haploid (23 chromosomes.) When it splits, this enables the zygote to have the proper chromosomes.

Why must DNA replicate prior mitosis?

Each daughter cell must have a copy of the full cellular genetic material or there would be no reason for mitosis. Once the cell gives rise to two daughter cell it is too late to replicate the genetic material then.

What is the DNA of mitosis?

There is no DNA of mitosis. Before mitosis, the DNA must be replicated, which occurs during interphase of the cell cycle.

How is DNA replication part of mitosis?

DNA replication actually precedes mitosis and occurs during the S phase of interphase. The DNA is duplicated but the two copies (sister chromatids) are still attached at one point called a centromere. At this point it resembles the familiar X shaped of the chromosome. During metaphase of mitosis tho (MORE)

How is DNA replicated-?

DNA replication begins with the "unzipping" of the parent moleculeas the hydrogen bonds between the base pairs are broken.
