Which phases of the cell cycle does interphase include?
Interphase includes three phases: G1 phase, where the cell grows and prepares for DNA replication; S phase, where DNA is synthesized and replicated; and G2 phase, where the cell continues to grow and prepares for cell division.
When and why does DNA need to be replicated?
When cells divide, the new cells produced must have a full set of genes in order to function correctly. Genes are made of DNA so it is necessary to replicate (copy) the DNA before the cell divides.
What would happen if cells with mutated DNA replicated uncontrollably?
If cells with mutated DNA replicated uncontrollably, it could lead to the development of cancer. This is because the mutations can cause the cells to grow and divide rapidly, forming tumors that can invade nearby tissues and spread to other parts of the body.
During which period is DNA replicated and cells grow?
Cells increase in Mass during G [growth] Phase and DNA replication occurs during S [synthesis] Phase.
What enzyme Cuts out the RNA primer on the replicated DNA molecule and replaces it with the appropriate DNA nucleotides?
The enzyme that cuts out the RNA primer on the replicated DNA molecule and replaces it with the appropriate DNA nucleotides is DNA polymerase I in prokaryotes and DNA polymerase delta in eukaryotes. This process, known as primer removal or primer excision, is essential for completing DNA replication accurately.
What happens when a cell under go mitosis?
Mitosis is broken up into 4 phases, Prophase, Metophase, Anaphase, and Telophase. During these phases the DNA, which was replicated during Interphase, split and 2 new cells are formed.
What would happen if cells with mutated DNA replicated?
Cancer.
What phase is interphase is the s phase?
S stands for synthesis. This is the phase in which the DNA is replicated in advance of the phases of mitosis.
Which phases of the cell cycle does interphase include?
Interphase includes three phases: G1 phase, where the cell grows and prepares for DNA replication; S phase, where DNA is synthesized and replicated; and G2 phase, where the cell continues to grow and prepares for cell division.
What is a characteristic of mitosis and not of meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
Where are mitochondria constructed?
They are not built. They replicate themselves in cells

If cells with mutated DNA replicated uncontrollably, it could lead to the development of cancer. This is because the mutations can cause the cells to grow and divide rapidly, forming tumors that can invade nearby tissues and spread to other parts of the body.
Why is it essential that DNA be replicated?
The cells that follow must be the same as the cells that they came from. You don't want a finger to grow out of your nose.
Do cells replicate or copy their DNA before going through meiosis?
Yes. The DNA is replicated during interphase before prophase I.
When is DNA duplicated and why is DNA duplicated?
DNA is duplicated during the S phase of the cell cycle, prior to cell division. DNA is duplicated to ensure that each new cell receives an exact copy of the genetic information, allowing for the accurate transmission of genetic material to the daughter cells.
How is recombinant replicated?
Recombinant DNA is replicated using host cells, typically bacteria or yeast, that have been engineered to contain the desired DNA sequence. These host cells are then grown in a lab setting under specific conditions that allow for the replication of the recombinant DNA. The cell division process allows for the production of multiple copies of the recombinant DNA.
