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
