when DNA replicates they can be separated by the enzyme helicase single strand DNA binding a proteins.one DNA stranderd incorsed liding strands which form 5 to 3 primates now there is no problem . but lagging strand makes a problem from 5 primes to 3 primes too. it forms a pieces called okazaki fragments. first the RNA primase lays down a RAN primer and then DNA polymerase 3 lays down new DNA. the process the RNA primers with DNA. finally DNA ligase links with okazaki fragments.

Where does the process of replication take place in the cell?
The process of replication takes place in the nucleus of a eukaryotic cell and in the cytoplasm of a prokaryotic cell.
DNA is copied during what process?
DNA is copied during a process called DNA replication. This essential process takes place before cell division and ensures that each daughter cell receives an exact copy of the genetic information.
How often does DNA replication occur in a cell's life cycle?
DNA replication occurs during the S phase of the cell cycle, which happens before cell division. This process typically occurs once in each cell cycle.
What is the purpose of DNA replication?
DNA replication is a necessary preliminary step for cell division, for both meiosis and mitosis. It creates the 2 chromatids that are found in chromosomes that are preparing to divide. By this process, the whole chromosome is essentially duplicated, but is still held together by a common centromere.
Is mitosis directly involved in the process of DNA replication?
No, mitosis is not directly involved in the process of DNA replication. DNA replication occurs during the S phase of the cell cycle, which is separate from the process of mitosis. Mitosis is the division of the cell's nucleus into two identical daughter cells, while DNA replication is the process of copying the cell's genetic material.
What is the process by which a cell makes a copy in meiosis?
Before meiosis begins, the cell copies its DNA in the process of DNA replication.
Where does the process of replication take place in the cell?
The process of replication takes place in the nucleus of a eukaryotic cell and in the cytoplasm of a prokaryotic cell.
Why DNA replication is needed before a cell divides into two daughter cells?
DNA replication is essential before a cell divides to ensure that each daughter cell receives an identical set of genetic information. During cell division, the original DNA is duplicated, allowing each new cell to inherit the complete set of instructions necessary for growth, development, and functioning. Without replication, daughter cells would lack the necessary genetic material, leading to potential malfunctions or cell death. This process is crucial for maintaining genetic continuity across generations of cells.

Why DNA replication needed a cell divides into two daughter cells?
DNA replication is necessary before cell division to ensure that each daughter cell receives an identical copy of the genetic material. This process is crucial for maintaining genetic information continuity across generations and ensuring proper functioning of the cells. Without accurate DNA replication, errors in genetic information could occur, leading to mutations and potential disruptions in cell function.
What is a process of cell replication means?
Mitosis
Which cell process the nucleolus involved in?
Replication.
What is general definition of replication?
Replication is the process of copying genetic material, such as DNA or RNA, to produce an identical or similar copy. In biology, it plays a crucial role in cell division, growth, and repair. Replication ensures that genetic information is passed on accurately from one generation to the next.

By this process, the whole chromosome is essentially duplicated, but is still held together by a common centromere.
Where does DNA replication form?
DNA replication occurs in the nucleus of the cell - just before the cell divides.
What the process of DNA replication is necessary before a cell?
DNA replication is essential before a cell divides, as it ensures that each daughter cell receives an identical set of genetic information. The process begins with the unwinding of the double helix by helicase, followed by the synthesis of new strands by DNA polymerase, which adds complementary nucleotides to each original strand. This results in two identical DNA molecules, each composed of one original and one newly synthesized strand. Accurate replication is crucial for maintaining genetic integrity and proper cellular function.
