Are cells and DNA the same thing?

We learned in biology class that every cell in the body has the same DNA. Whether a heart cell, skin cell or muscle cell—they all read from the same genetic blueprint. Now, scientists are learning there is more to the story.

Almost all of the cells in your body share the same DNA as was found in that first cell. Your DNA contains all of the information needed for making you. This information is stored in the over 20,000 human genes found in almost all your cells.

is this a psat question, if so do not cheat try your best.
