DNA molecules are extraordinarily long-an adult human has about six feet of DNA inside every single cell! Since all the genes are not
making proteins all the time, DNA condenses in order to protect itself.
Each DNA molecule wraps around proteins to form a structure called a
chromatin. In non-dividing cells, the DNA will stay in chromatin form.
When the cell is ready to divide, the chromatin will wrap around more
protein molecules to form rod-shaped structures called chromosomes.
While we call each molecule of DNA a chromosome, remember that
true chromosomes only form before cell division . Chromosomes come
in many sizes. In humans, chromosome 1 carries about 3,000 genes,
while chromosome 21 only carries about 300!
