This process is known as DNA replication. DNA is a double-stranded molecule, and this serves to the cell's advantage. Using an enzyme, the cell splits the DNA strands apart, and new strands are copied onto the two parent strands to form two identical new strands. The process is much more complicated than that, but that's what happens.

Is the process of duplicating chromosomes prior to cell division.?
DNA replication
Cytoplasmic division in animal cells involves all except?
DNA replication. Cytoplasmic division, also known as cytokinesis, is the process where the cytoplasm of a cell divides following nuclear division. It involves the formation of a cleavage furrow and the separation of the cytoplasm into two daughter cells. DNA replication occurs during the S phase of the cell cycle, prior to cell division.
Cell growth where a cell increases in size carries on metabolism and duplicates prior to division?
Cell growth involves an increase in cell size as well as the duplication of cellular components through metabolic activities. This process is necessary before the cell undergoes division in order to ensure that the resulting daughter cells receive a complete set of organelles and genetic material.
The faithful replication of DNA prior to cell division depends primarily upon?
The faithful replication of DNA prior to cell division depends primarily upon the enzyme DNA polymerase, which reads the existing DNA template and synthesizes a new complementary strand. This process ensures that each daughter cell receives an accurate and complete copy of the genetic information. Additional proteins and mechanisms, such as proofreading and error correction mechanisms, also play a role in maintaining the fidelity of DNA replication.
Why are germ cells diploid prior to their first meiotic division?
Germ cells go through DNA replication during interphase before their first meiotic division. This results in them being diploid, with two sets of chromosomes, in order to ensure genetic diversity in the resulting haploid daughter cells produced after meiosis.

What is the relationship between chromaids and chromosomes?
Normally a cells chromosomes are single strands - a bit like a pice of string. Just prior to cell division, a chromosome replicates (=makes another copy of itself) and these two copies are joined together at a point called the centromere. Each copy is now called a chromatid and being joined at the centromere make the familiar "X" shape, with each copy (chromatid) forming a side of the X and will have exactly the same sequence of genes down its length as the other chromatid (they are copies!). In cell division the copies (chromatids) will be pulled apart (X becomes > <) to become chromosomes in their own right.
What is DNA replication and what is its function?
DNA replication is the process in which the DNA is copied prior to mitosis. It's purpose is to prepare the cell for mitosis, which is the division of the nucleus into two identical daughter nuclei, usually followed by cytokinesis, the division of the cytoplasm.
How can mutation occurs in cells?
Mutations can be inherited. This means that if a parent has a mutation in his or her DNA, then the mutation is passed on to his or her children.Mutations can be acquired. This happens when environmental agents damage DNA, or when mistakes occur when a cell copies its DNA prior to cell division.
What cell is being obsorved when it shows formation of a contractile ring just prior to cytoplasmic division?
The cell being observed is likely a eukaryotic cell undergoing cytokinesis. The formation of a contractile ring just prior to cytoplasmic division is a key step in the process of separating the cytoplasm into two daughter cells. This contractile ring consists of actin and myosin filaments that contract to pinch the cell in two.
What happens to a cell's DNA prior to cell division?
It replicates.
A cell shows formation of a contractile ring just prior to cytoplasmic division Which cell is being observed?
Human fetal cells show formation of a contractile ring just prior to cytoplasmic division.
What happens to the DNA in your cells prior to cell division?
Cell division is a process in which a cell divides (roughly equally) to give two daughter cells. Therefore, there have to be two copies of the genome even before mitosis begins. When we look at the cell cycle, there are four distinct phases: G1, S, G2 and M. The S phase is where the DNA replicates. Once there are two copies in the genome, the cell goes through the G2 phase and then enters the M (mitosis) phase.
What part of the cell structure controls replication of chromosomes prior to cell division?
The nucleus of the cell contains the genetic material, including chromosomes, and it plays a critical role in controlling replication prior to cell division. Within the nucleus, specialized structures such as the nucleolus and proteins involved in DNA replication help regulate the process of chromosome duplication.
Last time cardinals won division?
Prior to the Cardinals' 2008 NFC West division title, that was 1975 when they were playing in St. Louis and in the NFC East division.
Should I detox prior to beginning a new diet?
Generally speaking you do not need to detox before starting a new diet, your body will go through a detox process itself. You can aid this process by drinking more water during the day.
Give an example of each process?
Sure! Here are examples of each process: Photosynthesis: Plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Cellular respiration: Cells break down glucose to produce energy in the form of ATP, which is used for various cellular activities. DNA replication: Prior to cell division, the cell copies its DNA to produce two identical copies. Translation: During translation, mRNA is decoded by ribosomes to produce a specific protein based on the sequence of nucleotides.
