•
It has many sugar units.
•
It can have up to two sugar units.
•
It has no sugar units.
•
It is also an oligosaccharide.
CONCEPT

What is chromatin?
•
A cell organelle that houses the DNA and controls activity within the cell
•
A condensed form of DNA that occurs when the cell is dividing
•
A form of uncondensed DNA found within the nucleus of the cell
•
