Transgenic Mice: How Genetic Engineering Has Changed Scientific Research

Genes can be rearranged in mice to make them express a gene from another species. This change in DNA can have various effects on the mouse, including changing its appearance and behavior. Scientists are now able to study transgenic mice quite easily because they quickly become available and relatively cheap.

What is a Transgenic Mouse?

Genetic engineering is a process of adding genes from one organism (a donor) into another organism (the recipient), in order to change the characteristics of that organism. For example, genetic engineering can be used to add genes from a different species of animal into a plant so that the plant will produce chemicals that are useful in industrial processes. Genetic engineering can also be used to change the characteristics of individual cells in an organism. This is called “transgenic” or “gene-modified” technology because the changes are made to the genetic material, or DNA, in the cells.

How are Transgenic Mice Used?

Transgenic mice are often used in scientific research to study diseases or test new treatments. They have been created using a gene from one species of animal (usually a mouse) and a gene from another species of animal (usually a rat). This process is called genetic engineering.

Transgenic mice can help scientists learn more about the effects of certain drugs or treatments on human cells. They can also help scientists study how genes control the development of tissues and organs.

Transgenic mice are also important for research into birth defects. By studying these defects in transgenic mice, scientists can develop methods for preventing them in humans.


Over the years, genetic engineering has undergone a dramatic change due to advances in technology. Nowadays, scientists can not only manipulate genes but also insert them into other organisms, such as mice. This allows for unprecedented levels of research that would otherwise be impossible. So if you’re looking for an in-depth understanding of a scientific topic, you should definitely investigate genetic engineering through the work of transgenic mice.
