WEAOPNS OF GENETICS, DNA-THE GENETIC MATERIAL
M.K.Bhelloria
Throat of Genetistics, Authentic and Reliable facts
We
are always desirous to know about the secret of life, biologists said that in
our body each and every character is expressed by a smallest unit of the cell
known as DNA. The discovery of the double helix
structure of DNA is to science what the Mona Lisa is to painting. It's been
called the single biggest discovery of all time. But it wasn't just stumbled
upon - it was a race. Specifically, it was a race between two teams of young
scientists working in Britain, as well as the esteemed chemist Linus Pauling,
based in California. Fifty years ago, James
D. Watson, then just twenty four, helped launch the greatest ongoing scientific
quest of our time. Now, with unique authority and sweeping vision, he gives us
the first full account of the genetic revolution—from Mendel’s garden to the
double helix to the sequencing of the human
genome and beyond. Watson’s lively, panoramic narrative begins with the
fanciful speculations of the ancients as to why “like begets like” before
skipping ahead to 1866, when an Austrian monk named Gregor Mendel first deduced
the basic laws of inheritance. But genetics as we recognize it today—with its
capacity, both thrilling and sobering, to manipulate the very essence of living
things—came into being only with the rise of molecular investigations
culminating in the breakthrough discovery of the structure of DNA, for which
Watson shared a Nobel prize in 1962. In the DNA molecule’s graceful curves was
the key to a whole new science. Having shown that the secret of
life is chemical, modern genetics has set mankind off on a journey unimaginable
just a few decades ago. Watson provides the general reader with clear
explanations of molecular processes and emerging technologies. He shows us how
DNA continues to alter our understanding of human origins, and of our
identities as groups and as individuals. And with the insight of one who has
remained close to every advance in research since the double helix, he reveals
how genetics has unleashed a wealth of possibilities to alter the human
condition—from genetically modified foods to genetically modified babies—and
transformed itself from a domain of pure research into one of big business as
well. It is a sometimes topsy-turvy world full of great minds and great egos,
driven by ambitions to improve the human condition as well as to improve investment portfolios.
Facing a future of choices and social and ethical implications of which we dare
not remain uninformed, we could have no better guide than James Watson, who
leads us with the same bravura storytelling that made The Double Helix one of
the most successful books on science ever published. Infused with a scientist’s
awe at nature’s marvels and a humanist’s profound sympathies, DNA
is destined to become the classic telling of the defining scientific saga of
our age.
