What do you mean by one area? If by one area you mean does it start at one area then stop and continue on another area then no, DNA replication is continuous and when it takes place it is the most important thing going on in the cell. The cells resources are directed at this process * DNA replication means copying the entire DNA molecule, so it involves the entire molecule, but not all at the same time. In bacteria (prokaryotic cells) replication begins at one point in the molecule and continues all the way round the circular molecule.
Beginning at just one place would take too long in eukaryotic cells; someone has calculated that our longest chromosomes would take about a fortnight to replicate, and we cannot wait that long! So replication begins at a number of sites along the length of the DNA molecule. At each replication site, as the DNA strands are separated there is a bulge in the molecule called a replication bubble. As replication proceeds these bubbles become longer, and eventually they merge into one another and the job is done.

Which best describes a difference between transcription and DNA replication A.Only transcription happens in the nucleus. B.DNA replication takes place in the ribosome. C.Transcription does not requ?
A key difference between transcription and DNA replication is that transcription occurs in the nucleus and involves synthesizing RNA from a DNA template, while DNA replication involves copying the entire DNA molecule to produce two identical DNA strands. Additionally, transcription only requires a specific segment of DNA, whereas DNA replication encompasses the entire genome.
Where does the DNA replication take place in prokaryotic cell?
Replication of cellular components such as DNA takes place within the cytoplasm or nucleoid which some prokaryotes have. A nucleoid is a primitive form of a nucleus.
What is meant by ori region in a plasmid?
The ori region, or origin of replication, in a plasmid is a specific sequence of DNA where replication begins. It is necessary for the plasmid to replicate independently within a host cell. The ori region contains the necessary signals for the initiation of DNA replication.
Describe the components of the replication machine.?
The main components of a replication machine include DNA helicase, which unwinds the DNA double helix; DNA polymerase, which adds new nucleotides to the growing DNA strand; primase, which synthesizes RNA primers for DNA replication to start; and DNA ligase, which joins the Okazaki fragments on the lagging strand. These components work together to ensure accurate and efficient replication of DNA.
Does DNA replication start at only one place in the DNA, or does it occur in many places at once?
DNA replication starts at multiple points along the DNA strand simultaneously. This process allows for efficient and rapid duplication of the genetic material.
Where does DNA replication takes place?
DNA replication takes place in NUCLEUS
Where does DNA replication take place?
DNA replication takes place in the nucleus of a cell.
Where does DNA replication take place in humans?
DNA replication takes place in the nucleus of human cells.
Where the cell does DNA replication take place?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
How many times does DNA replication take place in the process of meiosis?
only once
What are the areas on DNA where replication occurs called?
DNA replication begins in areas of DNA molecules are called origins of replication.
Where does DNA replication take place in the cell?
DNA replication takes place in the nucleus of a eukaryotic cell and in the cytoplasm of a prokaryotic cell.
Does DNA replication take place in the cytoplasm of eukaryotic cells?
No, DNA replication takes place in the nucleus of eukaryotic cells. The nucleus contains the necessary enzymes and machinery for DNA replication to occur accurately.
True or false replication start at one end of DNA molecule and proceeds to the other end?
False: DNA replication starts at origins of replication which can be anywhere on the DNA molecule. Replication is taking place at multiple origins at the same time.
Where does replication in DNA take place?
DNA replication takes place in the nucleus of a eukaryotic cell (plant or animal cell or the cytoplasm of a prokaryotic cell (bacteria).
