The GENETIKON project (Lexicon of genetics) covers terminology from the field of genetics bringing together the key terms and a systematically elaborated Croatian dictionary of this field of biology. As such it will not only contribute to the development of Croatian technical vocabulary, but could also facilitate communication among researchers and various professionals and technicians working in molecular biology and related fields. It could also prove tobe useful in education of students of natural sciences and biomedicine and help biology teachers present concepts from molecular and cell biology and genetics in a better and clearer manner. Moreover, GENETIKON could contribute to the popularization of this science since this collection of well-defined basic terms from molecular biology should also stir the interest of a wider audience that could use itas a sort of glossary.
