With the teaching of Biology in school, the acquisition of knowledge regarding the science of Biology is sought. The topics of the lesson that are presented in the National Examinations require a very good understanding of the curriculum, critical and integrative thinking, and additionally require knowledge that is not clearly analyzed in the textbook. Through this book, which has been written with special care and methodicalness, those parts of the curriculum that are not adequately analyzed in the textbook are covered. For this reason, in addition to the usual exercises found in the chapters of the textbook, it was deemed necessary to include, among other things, original exercises, selected examination topics, and especially exercises of increased difficulty. The book contains a total of 244 exercises. 84 of them concern "Genetic Material", 114 concern "Replication, Expression, and Regulation of Genetic Information", and 46 concern "Recombinant DNA Technology".
