Gene therapy is enjoying some success with treating diseases that cause blindness. Successful trials have taken place that have restored vision to blind individuals.
Genetic Engineering & Gene Manipulation
Learn about genetic engineering, gene manipulation and modification acheived by molecular cloning and transformation. You’ll also find discussions on the health of genetically modified foods and the ethics behind cloning and human genetic engineering.
Enzymes are the superheroes of biology and chemistry. They can start and speed up reactions, and nearly all are proteins. Enzymes catalyze chemical reactions and genetic engineering technology can give them a little boost to make them even more powerful.
Though most would find it hard to accept that the existence of genetically altered babies is no longer a dream of sci-fi novels and TV shows, the reality is undeniable. Almost 30 genetically altered babies were born in the US at several facilities, of which 15 were born in New Jersey.
This article takes a look at how gene regulatory networks function. Gene regulatory networks control mRNA transcription from DNA and the subsequent production of proteins. They oversee cellular functions and development. They are the reason why a biological organism is able to evolve and survive.
Knockout mice have taken the lab limelight for a number of years and contributed to great swathes of knowledge about human diseases. But they could be pushed aside by the creation of a knockout lab rat without a functioning immune system.
Since their creation in 1989, knockout mice have become invaluable tools for researchers tying to find out the functions of genes. But as good they are, there are limitations with using these genetically engineered animals.
Using the directed evolution method, you can create proteins and enzymes with specific properties for specific purposes in agriculture, industry and medicine. Directed evolution allows you to create these enzymes in a shorter period and it also helps us to understand the enzyme creation process.
Knockout mice are an invaluable research tool. They have played important roles in the study of many human illnesses and disorders including obesity, heart disease, and a range of cancers. But what are they and how do they help scientists unravel the molecular mysteries of disease?
No one is going to live forever, and there’s nothing we can do about it. Every living thing has a sell-by date. However, it may be possible to increase our time on this planet, or at least make our old age healthier by discovering, understanding, and manipulating longevity genes.
Ruppy is the world’s first transgenic dog and was created by a team of scientists from Seoul National University in South Korea. Her name is short for Ruby Puppy, and she and her four siblings all express a fluorescent protein which glows red under ultraviolet light.
The process of cloning is a controversial and emotive research enterprise, but one that has practical applications in agriculture, genetics, and medicine. Find out more about human and animal cloning, reproductive cloning and how cloning is done in our FAQ.
