Describe Why It Is Essential For Dna To Replicate Prior To Cell Division
Follow Report What do you need to know. As the genome the complete sequence of the DNA is an essential part of a cell it is necessary for the DNA to be duplicated prior to cell division.
The Cell Cycle Biology I
DNA replication will make the organism to.
Describe why it is essential for dna to replicate prior to cell division. So that each daughter cell will have 23 chromosomes b. If the DNA strand is found to be broken or damaged the entire process stops until it is. There is a complex system of proteins and enzymes that unravel the DNA double helix so that the DNA can be copied.
Here is a video which uses an animated tutorial to explain the process. Correct answer to the question Describe why it is essential for dna to replicate prior to cell division. If DNA isnt replicated cell cycle would be stopped at G2 phase checkpoint and mitosis will be blocked.
Why is it necessary for the DNA to replicate prior to cell division. Describe why it is essential for DNA to replicate prior to cell division. The important characteristic of DNA is its ability to make several copies of it.
Answers 1 Paulina 1 September 1129. DNA replication needs to occur because existing cells divide to produce new cells. Reproduction of cells and organism are dependent on DNA replication.
So that each daughter cell will have a complete copy of the genetic material c. What would happen otherwise Get the answers you need now. Through replication the DNA transfers the information necessary for creating an exact copy of it in the new cell.
The two daughter cells are identical to the. So that each daughter cell will have 46 homologous chromosomes d. Yes DNA also has to divide.
In Eukaryotic cells chromosomes are structures. This is achieved by the highly regulated process of cell proliferation. DNA replication is a precondition to a cell division.
In order to make sure each copy of the cell that is produced during. If a cell dies the body must replace that cell. DNA is like the instruction manual for building and operating a cell.
So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions. So that each daughter cell will have 2 sister chromatids. Each time a cell divides into two daughter cells its full genome is duplicated.
Each strand directs the synthesis of a. Each cell needs a full instruction manual to operate properly. To get cell up to S phase synthesis phase where DNA needs to be replicated it is mand.
The only way to replace the cells is to first copy the information that the cell contained. If a single cell dies it can be replaced through mitosis. For humans and other complex organisms this duplication occurs in the nucleus.
Survival of the eukaryotes depends upon interactions between many cell types and it is essential that a balanced distribution of types be maintained. Each cell needs to have DNA in it in order to function with the one key exception of a red blood cell which has no nucleus. Why is it essential for chromosomes to replicate before cell division occurs.
DNA Replication Prior to Cell Division. Chromosomes Cell Division Somatic cells undergo cell division through the process of mitosis. Cell division and growth.
The DNA helix unwinds and the strands separate to allow the enzymes used in replication to do their work. The cell divides into two and distributes each copy of DNA into the divided cells. The information stored in the DNA is essential for life.
The copy is created in order to continue the species. Describe why it is essential for dna to replicate prior to cell division See answers 1 Ask for details. During cell division the DNA molecule unwinds and the weak bonds between the base pairs break allowing the strands to separate.
In multicellular organisms it is the means of tissue growth and maintenance. The process of making copies of DNA strand in nucleus of the cell is called replication. In unicellular organisms cell division is the means of reproduction.
