All living things have DNA

The definition of "alive" is not set in stone. Biologists seem to have this debate often enough. A red blood cell has contains no DNA or RNA, but it is made by your body and is certainly a part of it. Some seeds can stay in their shells for hundreds of years without changing... and then grow into plants. Is the dormant seed alive?
Arguements about whether or not certain things are alive often are not about scientific fact. They are about the definition of the word "alive", which does not have a precise scientific definition on which everyone agrees. People can have personal opinions, but you will find no correct scientific answer to your question.
That is the truth, but your teacher may want you to say that living things all need water, can reproduce, and can make enzymes, or something like that. Who can ever tell with teachers?

Living things can feel, though not necessarily have feelings.
One would be upset if they saw a kitten being sawed in half with a chainsaw because a kitten has nerves and it can feel. However, if a pencil was sawed in half with a chainsaw, not many people would mind because a pencil is nonliving.

Virus can have DNA or RNA but they're not strictly living thing. So DNA or RNA alone can't be it. And there some sand particles said to self replicate. That's hard one. I think your teacher will probalby reasonable enough to take things like reproduction and adoptability or something like that.

Living things carry out "life processes", such as:
Respiration,nutrition ,excretion ,regulation,growth,metabolism (chemical activities),movement,reproduction, transport (like circulation),have a "life span".
Compare a frog to a rock; which one carries out all of the above?
You will find the answer to your question in detail in the first chapter of any biology book under "life activities" or "life processes".

You really don't know the difference?
Living things, plants, people, animals

living things have the five senses, and can respond to changes. non living things cannot. also, living things have DNA and are made of cells. non living things are made of atoms and molecules.

They're not... on the smallest sub atomic level everything is living.
