Since 2 daughter cells will be created during cell division, DNA must first duplicate itself so that each cell gets the same DNA as the parent cell. Then it condenses into chromosomes that are symmetrical, with each sister chromatid on either side containing identical information.

∙ 12y agoBefore mitosis can begin, the nucleus must make a copy or replice of it's chromatin, so that there are two complete sets of DNA. This step is known as replication.

∙ 9y agoBefore the cell can divide, the DNA itself has to replicate. This occurs so that the resulting cells can perform all the necessary tasks, having a full copy of the DNA.

Cells must copy their DNA before they do what?
Cells must copy their DNA before they can divide into new cells. Replication (of DNA) before division (of the cell)
Does the DNA must occur before a cell can divide?
Before a cell can separate, it has to unravel its chromosomes and clone all its DNA
What must a cell do before it can divide to a new cell?
It must make a copy of its deoxyribonucleic acid (DNA).
What organelle must temporarly break apart so that DNA can divide up?
Chromosomes
What must DNA do Before chromosomes can form?
DNA wraps around protein before chromosomes can form.

Does the DNA must occur before a cell can divide?

What structure in a eukaryotic cell must be divided before the cell can divide?
dna
What must a cell do before it can divide to a new cell?
It must make a copy of its deoxyribonucleic acid (DNA).
What must occur before replication can begin?
The replication of DNA occurs whenever the cell needs the S shape division. This happens since when we divide, enough DNA is needed to be pass on to our daughters.
When cells divide what portion must be divided exactly?
The DNA.
DNA replication occurs?
The Replication of DNA does occur before the cell can divide.
What must DNA do Before chromosomes can form?
DNA wraps around protein before chromosomes can form.
What organelle must temporarly break apart so that DNA can divide up?
Chromosomes
Does DNA replication occur before the cell divides?
the DNA poly-meres must add complementary nucleotides to the DNA
Why must DNA fragments be exposed to an alkaline solution before hybridization?
To denature the DNA
What must energy be turned into before it can be used?
dna
