9.1.4 Semidione and related radicals,ngs in other parts of this book. No attempt is made here, however, to give a comprehensive discussion of the issue. Besides, there is a lot to be learned yet. We try to give you some basic ideas for understanding the chemistry of this big universe and the tiny planet Earth.

9.1.7 Radicals from carboxylic acids,ne must do. One is that it should be able to duplicate itself or rather should be able to dictate its own duplication (replication). The second is that it must contain enough information to replicate the whole organism of which the gene is a part. Let us see how this is done in terms of chemistry.
