Because when a cell divides it creates something like a mirror image and to do this it needs to copy the most important part of the cell the nucleus (which holds the DNA) and that will determine what the cell needs to do.

When cell references are copied and adjusted for each new position each adjusted cell reference WHAT IS CALLED?
Relative Reference
It is important for chromosomes to be copied before cell division because?
DNA must be copied before cell division so that one complete copy of each chromosome ends up in each of the two daughter cells. Otherwise only one cell would end up with DNA, making the other cell.. well.. not a cell.
When a chromosome divides one sister chromatid goes to each what cell?
Daughter
Why it is important for DNA to be copied before cell division?
DNA must be copied before cell division so that one complete copy of each chromosome ends up in each of the two daughter cells. Otherwise only one cell would end up with DNA, making the other cell.. well.. not a cell.
What determines the nature of cell's work?
The Genes determine the nature of the cell's work....Each gene is a blueprint that directs the production.
After mitosis each identical daughter cell has a complete set of what?
DNA replicates before a cell divides ensures that each daughter cell has a complete set of genetic material They must have an identical set of DNA.
When a cell divides how much of the cytoplasm does each new cell get?
about half
Why do chromosomes double during prophase?
When a cell divides, each of the daughter cells should contain a copy of the entire genome. This is the reason why a copy of every chromosome has to be made so that one half can go into each daughter cell. If the parent call contained 23 chromosomes for example, during the synthesis phase of the cell cycle (of which prophase is a part), the total number of chromosomes will increase to 46 since each chromosome will be copied. When the cell divides to create two daughter cells, each daughter cell will contain 23 chromosomes.
The cell divides in half and the plasma membrane grows to enclose each cell in?
Cytokenesis
Why do chromosomes need to become 2 strands before the cell divides?
The second strand of a chromosome is a copy of the genetic information for that cell. There are 2 strands so that when the cell divides, there is one copy of each chromosome for each offspring cell.
Does Each cell in a human contain a different set of genes?
no. every cell in the body contains the same genes as every other cell in the body
When cell references are copied and adjusted for each new position each adjusted cell reference is called?
Relative reference
When cell references are copied and adjusted for each new position what is each adjusted cell reference called?
Relative reference
Why is DNA copied in the process of replication?
DNA replication occurs because there need to be two identical copies of DNA before the nucleus of the cell divides, so that each new nucleus has a complete and identical copy of DNA.
Why are chromosomes replicated?
so that when the cell divides each new cell has a full copy of the DNA
Why DNA replication needed a cell divides into two daughter cells?
DNA replicates before a cell divides to give a complete set of genetic instructions to each daughter cell.
Ends of chromosomes that get shorter each time a cell divides?
Telomeres.
