[Music]
genetic engineering is the process of
methodically altering the nature and
structure of an organism's genes using
methods like molecular cloning and cell
transformation
this process can result in a
considerable transformation of an
organism's characteristics due to the
manipulation of genetic material dna
which determines how every cell
functions
while genetic engineering can result in
better traits in organisms it can also
lead to undesirable after effects
let us first understand how genetic
engineering can benefit individuals pros
of genetic engineering first is better
varieties of crops scientists have
genetically engineered crops like tomato
potato rice and soybean to new varieties
with improved nutritional value and
better yield
the genetically modified strains can
grow on tough terrains making the area
suitable for cultivation
engineered seeds can survive in harsh
climatic conditions and are resistant to
pests
biotechnology the science of producing
genetically engineered foods can slow
down spoilage of perishable foods
resulting in the greater shelf life of
fruits and vegetables secondly we can
now create new substances genetic
engineering can be applied to create
totally new substances and food
nutrients
the genetic modification can increase
medicinal value of foods thereby turning
them into edible vaccines
third modification of human genes
genetic engineering can be used to
modify genotypes of humans before birth
this process can manipulate specific
traits in a person such as enhancing
positive traits like boosting longevity
and suppressing negative traits like
genetic disorders
the discovery of genes associated with
exceptional qualities in humans has
allowed genetic engineers to
artificially introduce genotypes to
modify the dna of human beings and
desirable functional and structural
changes in them
fourth fighting diseases some of the
deadliest diseases in the world have
resisted destruction till date
however genetic engineering could wipe
out these diseases forever from the
human race
genetic mutations are responsible for
some dreaded diseases in humans the
sufferance can end with active
intervention and genetically engineering
which can protect the next generation
from these problems
scientists are looking for a permanent
cure for terrible diseases with the help
of genetic engineering
fifth tackling diseases in unborn
children advanced medical technology has
enabled doctors to detect certain
problems in unborn children
prenatal examinations can detect whether
the child will suffer from genetic
diseases such as down syndrome or sickle
cell anemia
if these issues are detected doctors can
use genetic engineering to cure diseases
in children even before they are born
the infants would be born healthy with
no diseases present at birth
genetic engineering can help people who
are at risk of passing unawfully
degenerative illnesses to their
offspring
if people suffering from genetic
disorders give birth there are chances
that the children will inherit the
disease
genetic engineering can ensure that the
children born to these individuals live
healthy and long lives and do not carry
the disease to next generations
6. enhanced longevity medical science
had enhanced the lifespan of human
beings but there are certain illnesses
that can appear later in life and kill
individuals earlier than their expected
lifetime
genetic engineering can reverse body's
natural deterioration on a cellular
level improving the lifespan as well as
the quality of life afterward
in addition it could help individuals
become accustomed to the growing
inconvenience like global warming
thanks to genetic engineering people can
adapt to live in places that will be a
lot colder or hotter in coming time
apart from its multiple benefits genetic
engineering has exposed human race to
several disadvantages by allowing
scientists to tread into territories
that were better left untouched let us
have a look at those disadvantages
cons of genetic engineering first is
ethical and religious objections when
genetic engineering was introduced many
religions believed that the genetic
engineers were trying to play god and
forbade it to be used on their children
there are several ethical arguments that
believe that the diseases exist for a
reason
if humans fight against them and
artificially extend their lifespan the
planet will become overpopulated and
result in problems that cannot possibly
be predicted
second is genetic anomalies it is known
that genetic engineering can bring about
changes at the cellular level but what
about the safety of these changes and
repercussions of the slightest changes
scientists are yet to fully understand
the working of the human body and they
cannot predict what would be the result
of their actions
what will happen if erasing one disease
introduces another brand new and more
dangerous disease
if scientists genetically modify unborn
babies it could result in complications
like stillbirth premature birth or
miscarriage
third genetic diversity hampered
diversity is an important part of
evolution that results in the
continuation of fitter and better
species
genetically modifying species can have a
negative impact on genetic diversity
just like cloning
gene therapy is not an affordable
process and makes it impossible for the
common man to benefit from it
additionally some traits responsible for
introducing diversity in species may
eventually die out because of genetic
engineering
fourth long-term use of genetic
engineering an important thing to
consider is the scope of genetic
engineering the technique has been in
use for years but the question is how
far can it go
while many scientists have been
diligently using the process to
eliminate worst illnesses genetic
engineering has remained at the center
of controversy for altering the dna of
living organisms
it has worked wonders for many but will
it pan out real safe in the long run as
something that remains to be seen
fifth hamper dietary value genetically
engineering foods result from the
contamination of genetic makeup of crops
the engineered crops supersede natural
weeds but they might prove to be
dangerous for natural vegetation
unwanted genetic modifications can cause
allergies in crops and hamper their
dietary value while improving their
appearance and taste
6. entry of pathogens genetic
engineering in crops is performed
through horizontal gene transfer while
this process can boost disease-fighting
capability of plants it can produce new
pathogens
the disease-resistant genes can get
transferred to dangerous pathogens and
make them stronger
this shows that genetic engineering has
its own set of benefits and
disadvantages
it is up to the scientists using this
technique to apply it after weighing its
the pros and cons
