DNA replication begins when the two sides of the DNA molecule unwind and seperate, like a zipper unzipping.
What else can I help you with?
Before a cell can go through mitosis the DNA must replicate during intephase?
Replication
Why does a cell make a copy of its DNA defore it divides?
Because each cell needs its own set of DNA, there must be two sets of DNA present in a cell before it divides into two.
Cells must copy their DNA before they do what?
Cells must copy their DNA before they undergo cell division. This ensures that each daughter cell receives a complete set of genetic information.
What must happen before meiosis begins?
A duplication of the chromosomes is what must happen before meiosis can begin.
What must occur during S phase of the cell cycle so that two daughter cells can be produced during M phase?
During the S phase of the cell cycle, DNA replication occurs, where each chromosome is duplicated to produce two identical sister chromatids. This process ensures that when the cell divides during M phase, each daughter cell receives an identical set of chromosomes. Additionally, the integrity of the genetic material is crucial, so any errors in replication are typically repaired before mitosis begins.
Before a cell divides the DNA must duplicate itself by what?
Before a cell divides, the DNA must duplicate itself through a process called DNA replication. This process ensures that each new cell receives an identical copy of the genetic information stored in the original cell's DNA.
Does DNA replication occur before the cell divides?
the DNA poly-meres must add complementary nucleotides to the DNA
Before a cell divides it must first make an exact copy of all of its?
Before a cell divides, it must replicate its DNA to make an exact copy of all its genetic material. This ensures that each daughter cell receives a complete set of genetic instructions necessary for proper functioning. The process of DNA replication is crucial for maintaining the genetic integrity of the cell and passing accurate genetic information to the next generation.
What process MUST happen in the parent cell before it divides?
The parent cell must undergo DNA replication to ensure that each daughter cell receives a complete set of genetic information during cell division. This process ensures that each daughter cell contains the same genetic material as the parent cell.
What must happen before a cell divides?
Before a cell can dividess, it makes a copy of its DNA (deoxyribonucleic acid).
What must occur before replication can begin?
Before replication can begin, the parent cell must undergo a period of growth and DNA must be duplicated during the S phase of the cell cycle. Additionally, the cell must ensure that all necessary molecules and enzymes required for replication are available.
What does DNA have to replicate before a cell divides?
Before a cell divides, DNA must replicate, meaning it makes an exact copy of itself. This ensures that each new cell receives a complete set of genetic instructions.
Before a cell can go through mitosis the DNA must replicate during intephase?
Replication
Why does a cell make a copy of its DNA defore it divides?
Because each cell needs its own set of DNA, there must be two sets of DNA present in a cell before it divides into two.
What must a cell do before a cell divides?
It must make a copy of its deoxyribonucleic acid (DNA).
Why DNA have to replicated before cell division?
DNA replication must occur before cell division to make sure that the daughter cells are genetically identical.
Explain why DNA replication must occur before mitosis starts?
DNA replication must occur before mitosis starts to ensure that each daughter cell receives a complete and identical copy of the genetic information. If DNA replication did not occur before mitosis, the daughter cells would have only half of the necessary genetic material, leading to genetic abnormalities and potentially cell death.
