Genetic engineering’s heinous tactics

what is biotechnology engineering?

Rumours are circulating that parents may soon be able to practically “create” their children in the same way that you would design a webpage now. All of the qualities that distinguish people are encoded in their DNA. At some time, technology will advance to the point where it will be possible to modify DNA in any way wanted. As a result, it will be feasible to create human beings from scratch.

This is due to the fact that all of the qualities that distinguish individuals are encoded in their DNA. A particular bit of DNA determines hair colour, skin colour, bodily measurements, and so forth. At some time, technology will advance to the point where it will be possible to modify DNA in any way wanted.

What is biotechnology engineering?

In most current situations, biotechnology refers to molecular biology technologies. This is a collection of strategies for examining and changing the fundamental building components of life. Molecular biology is a branch of biology that studies the structure and function of macromolecules. DNA and RNA study is important to molecular biology.

The phrase “biotechnology” refers to a process that employs live creatures or portions of living organisms to create or change goods, enhance plants or animals, or create microbes for specialised use. However, the US Congress’s “Office of Technology Assessment” has a more comprehensive and often referenced definition, which describes it as “technologies that harness the power of biology to better human and other living things.”


Biotechnology has existed for some time.

The majority of agricultural products we consume today are the result of some sort of biotechnology. For example, yeast, a single-cell organism, is used in the production of beer. When you think about it, the preceding concept applies to many tactics that we currently employ on a daily basis. Biotechnology employs methods that have been available for thousands of years but are now being developed at a far quicker pace than was previously imagined.

Manipulation of DNA

Without a doubt, genetic engineering or DNA technology is a constantly expanding discipline that will most certainly offer up mind-boggling possibilities in the future. Although there are important distinctions between genetic engineering and DNA technology, the terms are used interchangeably in this context. But first, some background information from the field of molecular biology.


The information included in DNA determines a person’s eye colour, height, susceptibility to hereditary illnesses, and other characteristics

The genome refers to the whole of a cell’s genetic information. Estimates for the number of human genes vary greatly, but most agree on tens of thousands. Nonetheless, genes account for just roughly 3% of human DNA. The remaining 97 percent is less well known.

Genes are important because they provide information for the production of RNA, which serves as the blueprint for proteins. While RNA has many distinct forms and purposes, they all serve as blueprints for proteins, which ultimately produce the properties given in the DNA.

It amazes me that scientists were able to find out all of this information! But, of course, study does not end there; if we understand a system well enough, the concept of interfering with it comes quite readily. This is where DNA technology comes in, since it can be utilised to create new molecules that are resistant to chemical and physical manipulation.

Genetic engineering’s general pattern

The overarching objective is always to develop recombinant DNA (rDNA) – building an artificial DNA molecule that would not typically arise in nature. The procedure consists of numerous steps: First, the DNA fragments of interest must be identified and located. The components must next be extracted from the native DNA molecule. They are then integrated into a plasmid or vector, which we shall study into later.

Finally, they may be placed into the desired host genome, yielding a piece of rDNA. This overall pattern is also known as genome editing.

To further understand how this is accomplished, we will look at DNA cloning and sequencing procedures.


DNA cloning is the process of producing numerous copies of a given portion of DNA, such as a gene, by utilising enzymes that can cut DNA at a specified region known as a restriction site. The goal of DNA cloning is to create many copies of anything, such as a gene or strand of human DNA.

After removing a segment of DNA, it must be “pasted” onto a plasmid, which is often a circular DNA molecule – the host genome. We may employ DNA ligase, which are enzymes that can tie together bits of DNA, for this section.

When you combine several distinct bits of DNA, restriction enzymes, and plasmids in a lab, there is a high possibility that the reaction will occur a given number of times. It is critical to recognise that this is not done for a single DNA molecule, but rather for a sequence of interactions involving many different bits of genetic material.

The copied DNA is also present in the progeny of the transformed bacterium. It might be a gene that causes insulin production, or it could be an effort to clone human stem cells.


Images 1 and 2 depict the structure of a DNA molecule; the base pairs within the double helix can be seen in the upper figure. If you consider an organism to be a computer programme, the sequence in which the nucleobases emerge is the source code. The challenge of establishing the order of these base pairs is addressed by DNA sequencing methods.

Sanger Sequencing is a fundamental DNA sequencing technology. The molecule is broken into two single strands in the first stage. In a subsequent phase, the mixture cools and a small molecule – a primer – binds to the DNA single strands at a specified spot. Finally, the mixture comprises double-stranded molecules of all lengths. This allows the precise sequence of nucleobases from the original fragment of DNA to be reconstructed.

A few words on bioethics

Biotechnology’s capabilities generate a slew of ethical concerns. How should a certain technology be applied? Is it permissible to utilise it at all? Who has the authority to argue such issues? However, since this site focuses on technology, bioethical considerations are not addressed.

Prospects for the Future

CRISPR gene editing was developed less than a decade ago and is perhaps the most sophisticated genome editing tool available today. So, what is a reasonable forecast for future technologies and their applications? Here are few instances of how they might improve the lives of millions of people.


Changing DNA may obviously have a huge influence on medicine. This approach has the potential to cure a broad spectrum of inherited disorders. Furthermore, personalised medicine will swiftly advance to the point where medications are specifically matched to a patient.


Plants that have been genetically modified may be used in a variety of ways. Some argue that biotechnology offers existential threats to mankind. As available approaches grow more powerful, maintaining a solid ethical foundation will be critical. However, one thing is certain. It is a constantly expanding area that you should absolutely keep an eye on.
