Is carbon essential for life?

Life on earth would not be possible without carbon. This is in part due to carbon's ability to readily form bonds with other atoms, giving flexibility to the form and function that biomolecules can take, such as DNA and RNA, which are essential for the defining characteristics of life: growth and replication.
