What does a cell do before it divides?
it has to copy its DNA
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.
Why does a cell make a copy of its DNA defore it divides?
Because each cell needs its own set of DNA, there must be two sets of DNA present in a cell before it divides into two.
When DNA duplicates what does that mean?
DNA is in the nucleus of a cell. When a cell divides (mitosis) the DNA in the nucleus must first duplicate. Basically an identical copy of the cells DNA is made. This creates another nucleus in the cell with a copy of the DNA. The cell it's self then divides, separating the 2 nuclei. Each cell having one each.
How does a one cell make new cells?
the cell divides in two (and again and again), every 20 minuets in good conditions. The cell wont be an exact copy because before it divides it copies the DNA but sometimes it dosent match up and a the new cell will be mutated
Before a cell divides it must first make an exact copy of all of its?
A cell must make an exact copy of its genome before it divides. Genomes are the complete set of chromosomes present in a cell.
What does a cell do before it divides?
it has to copy its DNA
What must happen before a cell divides?
Before a cell can dividess, it makes a copy of its DNA (deoxyribonucleic acid).
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.
Why does a cell make a copy of its DNA defore it divides?
Because each cell needs its own set of DNA, there must be two sets of DNA present in a cell before it divides into two.
Why does a cell make a copy of itself before it divides?
So that the new cells have the same chromosomes as the parent cells.

Why mitosis importent?
Because it is the system by which plants and animals grow.When the cell divides a complete copy of the first cell's DNA must be replicated in the new cell.

Why are chromosomes replicated?
so that when the cell divides each new cell has a full copy of the DNA
Why does a cell make copy of its dna before it divides?
A cell makes copies of its DNA before it divides to pass on it's genetic information to the new cell. The parent cell needs to keep a DNA copy for itself to continue to replicate and adapt. That's right, all is not set in stone. Research shows DNA is adaptive, too. It responds to the environment, available food supplies, etc.
