Young readers learn how cells communicate with other cells and form living tissues.

They watch as viruses of a common head cold invade a human body and as bacteria cells invade the body through a small wound.

Children discover how the genes determine the characteristics of each new living being.

And also begin to understand how modern scientists copy and change genes within individual living cells, which make the altered plant or animal more resistant to certain diseases.

This book was written by Patrick A. Baeuerle, Ph.D., a renowned scientist in the fields of biochemistry and molecular biology, together with Norbert Landa, an experienced author of nonfiction children‘s books.
