Answer:
red blood cells, which contain no DNA in their mature state, and some immune system cells that rearrange their DNA while producing antibodies
Cell is the basic unit of life and they contain the needed information known as the DNA (genetic material) to carry out the basic life functions and processes.
All cells in the body essentially have the same genome except some red blood cells and some immune cells.
Red blood cells do not contain as DNA as they lack a nucleus so they are an exception to the rule. While some immune cells needs to reassemble their genome in order to aid in the production of antibodies.
Actually, gene expression comes in with this because cells become different as a result of the fact that a cell can decide which gene is to be expressed or not in accordance to its function it is supposed to perform.
