3The Blueprints of Life: Genomes, Genes, and DNA

No one doubts that frogs come from frogs, monkeys produce monkeys, and humans produce humans. Yet, except for identical twins, no two people in the world are the same when it comes to genetic factors. In other words, even though the information used to form humans is accurately transmitted to subsequent generations of their progeny, the information is somewhat flexible in changes during its transmission. What regulates this accuracy and flexibility then?
In this chapter, we will explain the formation of humans as living organisms from the genetic perspectives of DNA and genomes.
