In this article we will discuss about the definition and strategies of genetic engineering. Definition of Genetic Engineering: The deliberate modification in genetic material of an organism by changing the nucleic acid directly is called genetic engineering. Genetic engineering holds the potential to extend the range and power of every aspect of biotechnology. The techniques will be used widely to [...]
The following points highlight photoautotrophs and chemoautotrophs types of microorganisms that are based upon the source of electron. Type # 1. Photoautotrophs: Photoautotrophs include the photosynthetic bacteria, algae and green plants. These organisms fix carbon utilizing the energy of solar radiations through a process called photosynthesis. They are also called the primary producers of simple procedures because such organisms are [...]
