BIO732: Gene Manipulation and Genetic Engineering
“Genetic engineering is also called genetic engineering and refers to the genetic mutation of living things. It involves adding new DNA to an organism to introduce new features. A variety of microorganisms, plants, and animals have been created with new features through this process. All in all, in this study, we will learn about the basic techniques used for targeted genetic differentiation, their analysis by gel electrophoresis, and the enhancement of PCR. BIO732 Handouts pdf

BIO732: Gene Manipulation and Genetic Engineering
What is Genetic Engineering?
Genetic engineering is the process by which a person adds new DNA to a living organism. The goal is to add one or more new features to your existing one. However, there are several other terms that can be used to describe the technology, including genetic management, genetic engineering, genetic DNA technology, genetic modification, and so on.
Genetic engineering is applied to both basic and applied research. In basic research, it is used to study genetic mutations and to refer to prokaryotes, eukaryotes, and their bacteria. In applied research, it is used to develop microbial cultures that produce important metabolic products. It is also important to produce biodiversity, in environmental biotechnology and to treat genetic disorders (genetic therapy).
Genes and Genome
The genome is the complete set of living DNA, including all the genes. The genome contains all the information needed to build that living thing and allow it to grow and develop. The instructions in our genome are made of a unique chemical code of DNA. Both DNA and RNA contain two major purine bases, namely adenine (A) and Guanine (G), and two major pyrimidines. In DNA and RNA, one pyrimidine-cytosine (C) is common but the second pyrimidine in DNA is thymine (T) and in RNA uracil (U).
Gene, on the other hand, is a nucleic acid sequence needed to bind an active gene product that is polypeptide or RNA. A cell usually contains thousands of genes and the DNA molecules are not surprisingly large. The storage and transfer of biological information is the end of the known functions of DNA.

The Flow of Genetic Information
The flow of genetic information into a living system is called the central teaching of molecular biology (Fig. 1). Genetic information is encoded in duplicate DNA prior to cell division. Genetic information flows from DNA to RNA and then to proteins. This flow of information is based on a genetic code (sequence of three bases), which explains the relationship between sequence sequences in DNA or mRNA and the sequence of amino acids in a protein. The code is almost the same for all living things: the sequence of three bases, called a codon, defines amino acids.
Cell formation is the basis for many genetic engineering processes. The basic strategy for cell cloning is to move the desired gene from a large complex genome to a small, simple one. Fortunately, our knowledge of DNA chemistry and enzymology allows us to break down and join DNA in vitro DNA molecules. This process is known as in vitro recombination. Inhibitive enzymes, DNA ligase, and synthetic DNA are important tools used for in vitro synthesis. BIO732 Handouts pdf
