The delivery of DNA into animal cells is a fundamental and established procedure of genetic transfer. It has become a necessary tool for gene cloning, the study of regulation and gene function and the production of small amounts of recombinant proteins for analysis and verification. An experiment of Gene transfer helps to express the introduced genetic construct in the recipient cells or to inactivate or disrupt particular endogenous genes resulting in a loss of function.
Horizontal Gene transfer:
In horizontal genetic transfer, newly obtained DNA is incorporated into the genome of the recipient through either insertion or recombination. Recombination essentially is the regrouping of genes, such that native and new DNA segments that are homologous are combined and edited. Insertion occurs when the new DNA introduced into a cell shares no homology with existing DNA. In this case, the new genetic material is embedded between existing genes in the receiver’s genome.
Electroporation:
Electroporation is microbiology technique. This method was first used with animal cells in 1982. It is the transfection of cells following their submission to a pulsed electric field. The electroporation procedure is very simple. Cells are flooded with an electroporation buffer and exposed to a brief.
Genetic Transfer in Prokaryotes:
Generalized Recombination and RecA:
Homologous: Showing a degree of correspondence or similarity.
Genetic: Relating to genetics or genes.
Recombination: The formation of genetic combinations in offspring that are not present in the parents.
Bacterial Transformation:
Translocase: Translocate is an enzyme that assists in moving another molecule.
Expression: Gene expression is the process by which information from a gene is used.
Eukaryotic: Having complex cells in which the genetic material is organized into membrane-bound nuclei.
Exogenous: Produced or originating outside of an organism.
Transformation: Transformation is a genetic alteration in molecular biology. Which means a cell resulting from the direct uptake.
Bacterial Transduction:
Transduction: Transduction is the process by which DNA is transferred from one bacterium to another by a virus.
Lysogenic cycle: Lysogenic cycle is a form of viral reproduction involving the combination of the nucleic acid of a bacteriophage. With that of a host and followed by proliferation of the resulting prophase.
Lytic cycle: Lytic cycle is a very normal process of viral reproduction involving penetration of the cell membrane, lysis and Nucleic acid synthesis of the host cell.
Gene therapy: It can be defined as the purposeful transfer. So, Gene transfer is one of the key factors in gene therapy.
