- What is the genome?

- What kind of diversity characterizes it?

- How is each person shaped based on the molecular uniqueness of their genome?
- How important are genetic variations for the manifestation of genetic diseases and predisposition to clinical conditions and traits? - What is the genetic background of diseases? - Can their appearance be interpreted evolutionarily? - Is cancer a genetic disorder? - And ultimately, how important are the information we derive from the genome for health and disease?

The book you are holding in your hands addresses all these - important for every individual's life, as well as for the entire human species - questions and attempts to provide answers based on the knowledge we have today. The book uses about fifty short stories as examples, which aim to help the reader better understand the fascinating world of the genome, but also to serve as a starting point for further exploration and information.

In the journey towards understanding the hidden truth, scientific knowledge is constantly enriched, revised, and sometimes led to common ground - always through fruitful debate. The stories in the book are based on the knowledge we have today; however, as Shakespeare says in Troilus and Cressida: "What is past is prologue." This edition, therefore, is presented to the reading audience with a certain reverence - the reverence that stems from our degree of ignorance.
