We usually hear the controversy related to cloning. Some scientists call it the next big thing in science other hand, many organizations, politicians and religious leaders oppose the concept of human cloning. And it creates so much of the confusion. Why so much of controversy for a scientific research? Why so much of fierce oppose from religious leaders for a scientific invention which is solely indented to benefit humans? What is the big risks involved, which are making many people scared about human cloning?
Let’s try to find out the every single nitty-gritty of human cloning. I guess you are read. So, here we go.
So what is cloning?
Cloning is simply copying. Like you copy a drawing on your page.
Example-Identical twins. Yup! They are clones because they are copied to each other. Their clone creates naturally when cells divide in the womb. It means cloning can be happen naturally as well as artificially too.
Yo! So what is human cloning?
It’s like creating something which is the copy of the human whom scientists clone. Human cloning, is asexual (No sperm and egg meet) production of a new human organism that is identical to the human being whose DNA is used for the cloning. Its asexual production and here no sperm directly meet to egg.
How human cloning is done?
For human cloning, researchers take someone’s DNA whom they want to clone. It can be extracted from a skin cell or a hair. Then they insert it into an unfertilized human egg from which the existing DNA has been removed or inactivated.
After a couple of chemical tweaks, the egg cell, with its new nucleus started to behave like a freshly fertilized egg and started developing into an embryo. Later, this embryo gets implanted into a surrogate mother and it got cloned. Human cloning is achieved by a technique called as somatic cell nuclear transfer (SCNT).
John Lennon cloning
Jhon Lennon was British Pop legend of who funded the Beatles. He was assassinated in 1980.
Some Canadian dentist has a tooth of this pop legend and they want to clone it. Means they want to make a clone of Lennon, which will be genetically the same John Lennon of the 70s. Interesting. Isn’t it???
Benefits of cloning
Defiantly Cloning will bring out many medical advances. In fact, it will start a new revolution in medical science. A few exciting benefits of cloning are mentioned below.
1-With the help of cloning, it may be possible to reverse the aging process, someday. It means you can technically become younger whenever you wish. All you need to do is to create a clone of yourself for whatever age you wish to. Doctors will just copy your cell and make a new one with the age zero implanted into them. Suppose you are 60 years old, and you want to be 20 years old again. So the doctor will cloned your cell and now you will be just 20 years old.
Literally cloning would allow humans to live to an age they wish and they can die when they are ready to die. Even it will eliminate the fear of old age death. What a scientific advancement. Isn’t it??
2-Cloning can be used to grow organs or tissue to remake the damaged cells of our body.
It will cure many dangerous diseases and literally we can get rid of almost all disease.
3-It can lessen the chance of heart attack.
Doctors may treat heart attack victims by just taking out their heart cells that are damaged and some of the cells that are healthy. Then by cloning those cells and putting them in the parts where the damaged cells are, they would make a healthy heart. This could minimize a lot of deaths.
So finally cloning is good. So let’s do it. Why so much of hue and cry?
Technically, cloning seems very good, but there are many issues which need to be addressed properly.
1-Cloning involves a grave ethical issue. Technically it creates a human life solely for the purpose of destroying it. You create a clone and then kill it for organs which will be implanted in someone else.
It is just like growing vegetables. Here, scientists are growing organs just for use. Many religious organizations call it unethical as it uses a human embryo merely as a means to an end.
2-The children who born after cloning always born with severe deformities and there are a very rare chance to survive them.
Why it happens so? It happens due to missing, crucial interactions between the sperm and egg. It results in some serious genetic reprogramming errors. This leads to random, widespread genetic ‘imprinting’ and ‘epigenetic’ defects in cloned, which causes cancer.
3-The biggest setback of cloning is that when a cell derived from cloning is injected back into the donor, they got rejected because of epigenetic mis-expression.
Means a healthy organ developed by the clone body will most probably be rejected by the healthy body for which it was grown. Then how can you treat such disease if the body is not accepted the clone developed organs?
Finally, we must say it will take time to understand the all aspects of cloning. Over the years scientist may find solutions to these all concerns and cloning may play a wider role in the development of mankind.
