Abstract
Does life exist beyond our planet and, if so, is that life comparable with life forms we know here on the Earth? These are some of the most fascinating questions facing science today–particularly astrobiology, the study of the origin, evolution, Distribution and Destiny of Life in the Universe.

This remark is true for eubacterial cell walls, but strictly speaking it cannot be considered an exception to protein synthesis, because these peptides with D-amino acids are not synthesized at the level of the ribosomes. cf. also Glossary, “amino acids”, “phospholipids”, “biochemistry”, “chirality” and the “genetic code”.
