Genes were unknowingly discovered in the 19th century by Gregor
Mendel, a Czechoslovakian monk. It was later established that genes
are made of DNA, a biological compound found in tiny thread-like
structures called chromosomes that are located in the nuclei of all
cells in our bodies. DNA consists of chains of entities called
bases of which there are four in nature. DNA consists of long
chains of bases (sometimes referred to as DNA sequences) that are
joined in any order, but the precise order and length of which
constitute different genes.Many (but not all) genes carry a code
called the genetic code, a code that instructs the synthesis
(manufacture) of the many hundreds of proteins that we require to
survive and execute the many functions of life. The genetic code
was deciphered in relatively recent years and is considered one of
the most significant discoveries in the history of biology.Genes
that encode instructions for the synthesis of proteins and those
that regulate the manufacture of proteins comprise a mere two
percent of our DNA. Despite our extensive knowledge of biology and
the sub-discipline of molecular biology (the study of biology at
the molecular level), the function (if any) of the rest of the DNA
in our cells is unknown.Research about genes and DNA has in recent
years spawned an endeavor referred to as the Human Genome Project,
an international collaboration that has successfully determined,
stored, and rendered publicly available the sequences of almost all
the genetic content of the chromosomes of the human organism,
otherwise known as the human genome.DNA sequences that are unique
to every person on earth have been discovered (DNA fingherprints)
and are now used for identifying criminals. The book relates a
specific example of identifying a criminal who murdered two
women.This is the first and only book that we are aware of that
educates non-biologists about genes. It is written in a style and
uses a vocabulary that can be comprehended by the average reader
who knows very little if anything about genes.
