The Truth About Ourselves
The human genome sequence has been completed
and shows some surprising findings. Despite having one-third less genes
than estimated, human beings are still very complex. With access to disease
genes, medicine and diagnostics will be revolutionised. However, this
will also raise ethical questions on cloning and genetic privacy.

In Hell
Four weeks after the earthquake, Gujarat is still
coming to terms with the devastation. True grit is emerging from the rubble
but it will be some time before lives are rebuilt. INDIA TODAY's teams
went out across these death zones, capturing stories which record this
renewal.

Profitable Loss
36 With over 90,000 employees opting for the
VRS scheme, PSU banks are set to get over their problem of overstaffing.
But is it going to make banks more competitive in this age of automation?
Besides, it is also going to cost more than Rs 7,500 crore and will deprive
the banks of skilled workers.

Spreading Terror
The attacks on Delhi's Red Fort,
the Srinagar airport and the city's police control room show the Lashkar-e-Toiba
is increasingly catching the Indian security forces unawares-and emerging
as the most daring terrorist group from Pakistan.

COVER
STORY: HUMAN
GENOME
ETHICS
Can
man play God now?
So are we going to see a superhuman? Or a factory that churns out your
clone by the hundreds? Hate to deflate
the hoopla folks, we are still a long way from playing
Dr Frankenstein, leave alone God.
The
human genome sequence has been completed at a time when cloning of various
animals has become routine. The decoded sequence lays open to the public
information about all human genes. So can we manipulate our genes to provide
superclones? "Theoretically, yes," says Bainbridge, "but
it's very, very unlikely." It would be impossible to control the
multiple roles of genes. As Subramanian points out, "Our understanding
of the complexities of life just based on the sequence is quite trivial
at this point even though we have the blueprint in front of us."
Adds Nusbaum: "We have to remember that cloning does not bring a
person back. Environment has an effect. Genes are important but it's about
half the story. Your genes might determine that you could be a seven-footer,
but it won't happen without adequate nutrition." Genes, in other
words, define potential. It's the environment that ensures that potential
is fully met. Also only 1.5 per cent of the entire genome contains genes.
The rest, dismissed so far as "junk DNA" of no purpose, could
actually be extremely important in controlling the gene so that it expresses
at the right place at the right time. Scientists insist there is no room
or reason for scare stories.

cloning may be very difficult as environment is a key factor |
Ethical issues
are now a major concern for all scientists. Rather than cloning, a greater
threat comes from lack of privacy, says Nancy Lane, a bioethics expert
and professor of biology at Cambridge University. Like an id, a person's
gene sequence record can be made available on tap. In the near future,
this means an insurance company, for example, may charge a higher premium
from a person who shows a susceptibility for developing hypertension.
Or at the work place, Darwinian selection may be replaced by managerial
selection as employees are hired or fired on the basis of their potential
as seen from their genetic profile. "Educating the people is the
best way to protect them," declares Nusbaum. Not just the public
but governments too. Education must go hand-in-hand with legislation and
strict enforcement of law. Genome scientists are already lobbying governments
in the US to form regulations on genetic privacy. The maturity with which
we handle such powerful knowledge will determine the future of the human
race.

"enormously exciting" next book, The White Moghuls in
