The Cell Works:
Children
look within a cell's nucleus and learn about the double-helix structure of DNA,
as they learn how cells communicate with other cells, form living tissues, make
fresh cells, and build into the organs and organisms that all living beings
consist of, according to their gene patterns.
Introduces
the world of DNA and genetics, explaining the processes of cells, chromosomes,
and proteins, and discusses twins, genetic mutations, and cell diseases
Looks
at the new science of genetic engineering. Young readers 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. But this is only one of many avenues of discovery in this exciting
field.
Young readers watch as
viruses of a common head cold invade a human body and as bacteria cells invade
the body through a small wound. These are the body's villains, but they are
fought off and finally overcome by hero antibodies-- produced by our bodies to
protect us from harmful microscopic invaders.
