DNA EXTRACTION FROM KIWI ISGR SCIENCE Aalah Yousif‚ Ella Sobek April 27‚ 2012 Background All living organisms (plants‚ animals‚ and bacteria) are made up of cells. Any cell consists of many parts but the parts that play the key roles are the nucleus‚ cell membrane‚ and cytoplasm. The nucleus is like the “brain” of the cell (that also contains DNA). The cell membrane is like a wall that guards the cell. And the cytoplasm is a jelly-like substance which contains other smaller organelles like
