🧬 The Controversy of Cloning and Its Impact on Nature's Balance

The second paragraph explores the topic of cloning within bioethics, questioning the morality and practicality of creating human clones. It highlights the potential negative consequences of unregulated cloning, such as overpopulation, increased disease transmission, and the depletion of resources. The paragraph also discusses how cloning could disrupt the natural genetic diversity by relying too heavily on a single gene pool, leading to a loss of genetic vigor.

Keywords

💡Conjoined twins

Conjoined twins are siblings who are physically joined together, often sharing organs or body parts. In the script, this concept is used to illustrate the complexity and ethical dilemmas that can arise in medical scenarios, such as the decision to separate twins knowing one may not survive. It highlights the difficult choices that bioethics must address.

💡Bioethics

Bioethics is the study of ethical issues arising in the fields of biology, medicine, and health care. It is central to the video's theme, as it discusses the ethical implications of transgenic organisms and cloning. The script mentions bioethics as a means to navigate the moral challenges posed by advances in biotechnology.

💡Transgenic organisms

Transgenic organisms, also known as genetically modified organisms (GMOs), are those into which a gene from one species has been inserted into another species' DNA. The script discusses transgenic mice and crops like golden rice, which are engineered to contain desired traits, raising ethical questions about the manipulation of natural genomes.

💡Genetic engineering

Genetic engineering is a technique used to alter the genes of an organism, typically with the aim of giving it new abilities or characteristics. The video script uses genetic engineering as an example of a biotechnological process that can be used to study genetic disorders and create transgenic animal models.

💡Genetically Modified Organisms (GMOs)

GMOs are organisms that have had changes made to their DNA using genetic engineering techniques. The script discusses the potential benefits and risks of GMOs, such as the production of golden rice with enhanced Vitamin A content and the unknown long-term effects of GMOs on health and the environment.

💡Golden rice

Golden rice is a type of genetically modified rice that is biofortified with beta-carotene, a precursor to Vitamin A. The script uses golden rice as an example of a transgenic crop that can address nutritional deficiencies, while also raising questions about the ethical considerations of modifying natural food sources.

💡Ethical concern

An ethical concern refers to a situation or action that may be morally questionable or problematic. The script frequently refers to ethical concerns in the context of creating transgenic organisms and the potential risks and unknowns associated with GMOs.

Transcripts

Imagine a couple blessed with twin babies who are conjoint.

Now if they are to be separated, then one of them is sure to lose

life.

But raising the conjoined twins is not only difficult for the parents, but even

for the kids themselves!

So what should be done in this case?

These questions give us goosebumps!

But they are always a part of the medical field.

And how are the answers to such traumatising questions found?

Well, although we cannot really answer such questions completely, but still to

reach the best conclusion, we have the concept of BIOETHICS coming to our

rescue!

In the previous videos we learned about the Transgenic organisms which are

produced and used for human benefit.

But the production of transgenic animals comes at the cost of disturbing the natural

genome of those organisms.

So do you think this is morally correct?

You may say no!

We should not use organisms for our selfish motto!

Okay… so how do we test the newer medicines?

As the disease or disorder intensity is increasing exponentially,

so is the need for newer and more efficient medicines!

So if there are no model organisms, then testing medicines will not be possible.

So how will new medicines be discovered and used?

That indicates the need of using model organisms!

So what should be done ideally?

There is no single answer for this actually.

And hence, for these types of concerns we have

the field of bioethics.

Now let us first understand what Bioethics is!

It is simply the area dealing with ethical issues in the field of Medicine or

any other biological studies.

In this video, let us learn about bioethics in the field of biotechnology.

Let us begin with the same point that we discussed a few minutes

back...Transgenic organisms!

Genetic engineering enables us to study the various genetic disorders.

And for these types of studies, transgenic animal

models, like the Transgenic mice are developed.

Transgenic animal models are Developed for Particular genetic disorder

These animals, as we know are called Genetically Modified Organisms or GMOs.

And just like animals, plants are also modified.

So the transgenic crops produced also have qualities that we desire!

Just like the Golden rice for example!

It contains wholesome amount of Beta-carotene,

which is the precursor of Vitamin A. When consumed, the compound gets converted

to Vitamin A in the body.

Thus, the transgenic rice variety is a boon to areas

hit with Vitamin A deficiency.

But if the organisms are so beneficial to us, then is their production really an

ethical concern?

Yes!

That is the other side of the coin!

GMOs are known to produce several compounds, among which, a few can be toxic

or allergenic in nature.

We cannot ensure that these untraced compounds would not harm us.

Thus, there are several hidden risks attached to

this.

There can be possibilities that the GMOs turn out to be actually more harmful

rather than being beneficial.

The long term side effects of GMOs are still unknown.

Also, as we know that transgenic organisms have a completely different gene pool

from the wild varieties.

So at the species level, we disturb the genetic composition

of those organisms!

Do we really know what impact this can create several years

later?

What can happen if the transgenic genes sustain in the gene pool forever?

And what if natural genes are lost?

There are many other questions that emerge as we go deeper in this discussion!

Hence, making “transgenic organisms” is an ethical concern!

So what is the solution to this?

There is no fixed solution for this, but yes, there are few

regulatory bodies which glance at the various activities in the field of

biotechnology.

Now let us talk about one more hot topic in bioethics...that is Cloning!

We know that cloning in biotechnology deals with the process of making exact

copies of biomolecules or organisms.

How about Human cloning?

The idea sounds cool!

But that is not so great in reality!

Preparing human clones without regulation would definitely lead to

serious concerns, like overpopulation, increase in diseases, exhaustion of limited

resources and many more!

Also, this can act against the balance of nature.

We know that nature promotes variation in gene

pool of organisms.

Cloning can lead to utilisation of the same gene pool constantly,

thus leading to a loss of vigour in the genes.

And there are many other issues which pop up with the process of making clones!

Thus, the question whether cloning is favourable or not still remains unanswered!

For all such questions, which literally churn our minds, the only option that comes

to our rescue is Bioethics!

There are several rules and regulatory laws laid under

bioethics, that help us make wise decisions as we stumble upon heart wrenching

obstacles!
