Students usually have some confusion about DNA.
1. Many people think that DNA is only in the blood. They've heard of having a blood test to find out about the genes or paternity, and they think that's the only place to get DNA. Actually, an organism has a complete set of DNA in each cell. (There are a few exceptions like the human red blood cell that doesn't have a nucleus at maturity.)
2. Most people don't realize that DNA tells how to make the body's proteins, and then the proteins handle the rest of the instructions. The DNA doesn't tell how to make certain fats, for instance, but it does have the instructions for making the enzymes that will control the process of assembling the fats.
3. Many people think that the DNA is always in the form of chromosomes. Actually, the chromosomes only appear when the cell is preparing to divide. Otherwise, DNA is in the form of chromatin -- a loose mass of DNA that can easily be unwound and copied.
4. If you ask what DNA tells, usually the first answers are eye color and hair color, but DNA has far more information than that. It helps to look at a map of the genes that have been found on the various chromosomes. Rather shocking.
People think everything is DNA but the thing is that some things arn't

I do not really understand your question, but maybe what you meant to say is: "What are things that get confused with DNA?"
If so, then I would say that sometimes people confuse DNA with RNA.

i might confuse DNA with
1. RNA strands, especially after hybridization
2. polypeptide with significant secondary structure, eg alpha-chains in collagen
