A Closer Look at the Nucleus:
DNA is the blueprint for life.
A cell's DNA contains all of the
information necessary to make
a new cell and carry out its life
A cell's DNA normally exists in
long, coiled, spaghetti-like strands
inside the nucleus.
Each individual strand of DNA is called a
Before a cell can divide to
form two new identical cells,
it must make an exact copy
of each chromosome
Chromosomes in Mitosis
The process of cell division is called mitosis
When a cell divides, the chromosomes condense
and become visible
Chromosomes in Mitosis
After the cell is finished dividing, the two new cells
are called daughter cells
Each daughter cell contains one copy of every
chromosome from the original cell.
