Transgenic Animals

Introduction 

It has been very long since the experiment on the various genes of animals has started. Now, mostly the animals that are used here are the ones who do not cause any type of destruction or are fatal in any way to mankind. The most commonly used animal in this process is the mice. These generally do not cause any problems for mankind and are very quiet when they go about things. 

The process of transgenicity 

When any foreign gene is mixed with the original genes of any animal then they are called transgenic animals. Mostly these are mice, as mentioned above but there are other examples also. This process is usually carried out when the changes are supposed to be made for the improvement of that breed of the animal. There are many things that can be improved in a particular breed of the animal-like the body texture and the skin colour. 

Now there are two types of reactions generally to this. First, there is a reaction that includes discovery like when one gene is mixed with the other gene then an entirely new animal can be found in the body of the primary animal that adapts it well and if a new animal is found then obviously there is a discovery. 

But the second reaction is death. There have been many cases over the past that involve accidents involving the death of the animals. As a result, it leads to the death of that animal as every time the new gene cannot be compatible with the original species of the animal. 

Reason behind transgenicity 

Some of the reasons behind transgenicity are that it might lead to the overall development of that animal as sometimes if we merge the DNA of a small animal and a large animal, it can lead to the change in eating habits of that particular animal. 

Hypothetically, if we consider the example that if we merge the DNA of a lion and a mouse then as we know that the lions are carnivores and they usually feed on the flesh of the animals as well as non-vegetarian food whereas mice do not eat such things. So if we merge the DNA of the lion and mice, it can lead to multiple changes in the species of the mice like the type of food that the mice eat, and they can also change their eating habits like the lion and can start to feed on the flesh of dead small animals like the lizard and various other insects. 

Why transgenicity? 

Transgenic animals are a special breed that does not exist much and the reason behind this is the fact that most of the experiments in this context fail and hence scientists generally are scared to experiment much in this field. The most famous example of transgenic animals is Dolly, the sheep 

Dolly, the sheep 

As mentioned above, this is the most famous example of the transgenic animals. This breed of the sheep is the first mammal of this size to have been cloned. It happened in the late twentieth century when this was an upcoming field and most of the scientists then were hopeful of achieving something big in this field. 

Basically, if we are to go into this example of transgenic animals, then we would have to understand that the Dolly was a clone of two different breeds of sheep, mainly the Scottish Blackeye and the Finn Dorset. This was actually the first egg that was kept in the womb of the Scottish Blackeye and hence when it was produced, it looked like an exact carbon copy of the Finn Dorsett breed. The clone that was used was of an adult mammary gland cell. 

Even after its birth, Dolly lived a healthy life even after having functioning organs like the liver, lungs and the heart of a mammary gland cell. Since the success of this experiment, a lot of new experiments were tried but none of them came out to be as successful as this and so even after being the first experiment in this field, it still maintains to be the one that was the most successful and is even remembered today after so long. It would be right to say that the concept of transgenic animals is still alive today because of this discovery. 

Uses of Transgenic Animals 

There can be many uses of transgenic animals but some of the most important definitions of transgenic animals are like the constant tendency to want the best of the products and so the process of trangencity enables one to get the best breed of a particular animal. 

This process also helps to gather a lot of information on the different types of gene cells as most of them are used to dominate other small animals and see the change in their lifestyle and habits. So all in all, the concept of transgenic animals also tells us how a particular gene cell would react with other cells. 

Conclusion 

The process of transgenic animals is one of the most thorough processes but it involves a lot of risk in it as the success ratio in this field is very less. So if you are willing to work hard then only you should consider going into this field.
