What is Rearrangement Reaction? The term “rearrangement” is used to describe two different types of organic chemical reactions. A rearrangement may involve the one -step migration of an H atom or of a larger molecular fragment within a relatively short lived intermediate.
- Biotechnology can be defined as the use of microorganisms, plants or animal cells or their components to produce products and processes useful to humans.
- Principles of biotechnology are based on the concept of the following techniques: (i) Genetic engineering is the technique to alter the chemistry of genetic material (DNA/RNA), to introduce these into another organisms and thus, change the phenotype of the host organism.
- The techniques of genetic engineering include the following: (i) Creation of recombinant DNA by combining desired genes. (ii) Gene transfer. (iii) Maintenance of DNA in host and gene cloning.
- Construction of First Artificial Recombinant DNA. (i) It was achieved by linking a gene encoding antibiotic resistance with a native plasmid (an autonomously replicating circular extrachromosomal DNA) of Salmonella typhimurium.
