Imagine a synthetic life form created in a lab that uses a novel information storage molecule distinct from DNA or RNA, but still exhibits heritability and undergoes evolution. Which of the following aspects of the current definition of life would MOST require reconsideration in light of this discovery?
The requirement for cellular structure
The dependence on carbon-based chemistry
The specific molecular basis of heredity
