Quote from the Book I am Reading, Life on a Young Planet

"Despite an almost bewildering diversity of form and function, all cells share a common core of molecular features, including ATP, DNA, RNA, genetic code, molecular machinery for transcribing genetic information from DNA into RNA, and more machinery to translate RNA messages into proteins that provide structure and regulate cell function."
