إذا شبهت الذرة ونواتها والكتروناتها بالنظام الشمسي المصغر؛ فإن الخلية وما تتركب منه من نواة، وعضيّات (أعضاء صغيرة)، أشبه ما يكون بمجسم للكون الفسيح. وقد شكل اكتشاف الحامض النووي المنزوع الأوكسجين أو (D.N.A) شكلاً وتركيباً ومواصفات حلقة أخرى في سلسلة التقدم الحضاري، ولا شك أن هذا الاكتشاف الأخير مهد الطريق لبناء علم الوراثة، على أسس راسخة، حيث أيقن علماء علم الوراثة أن الجين هو المسؤول عن نقل المعلومات والخصائص الوراثية عبر الأجيال. يطرح الكتاب هذا الموضوع على بساط البحث ويتتبع مراحل هذا العلم حيث بدأ ببحث الكروموزومات، (D.N.A) والجينات وانتقال الميزات الوراثية أثناء الانقسامات الخليوية. ثم تطرق إلى وسائل تطوير الأنواع النباتية والحيوانية وانتهت إلى دراسة التكاثر، وتفصيل التجارب في عمليات الاستنساخ. وقد عمد إلى استعمال المصطلحات الأكثر شيوعاً، في العالم العربي وما يقابلها في اللغتين الإنكليزية أو الفرنسية، لتقريبها من فهم القراء.
