Gene delivery is the process of introducing foreign genetic material, such as DNA or RNA, into host cells. [1] Gene delivery must reach the genome of the host cell to induce gene expression . [ 2 ] Successful gene delivery requires the foreign gene delivery to remain stable within the host cell and can either integrate into the genome or ...
Alternatively, DNA can be introduced into a genome through NHEJ in the presence of exogenous double-stranded DNA fragments. [10] Homology directed repair can also introduce foreign DNA at the DSB as the transfected double-stranded sequences are used as templates for the repair enzymes. [10]
If the gene expresses close homology to a known gene in another species, then it could be isolated by searching for genes in the library that closely match the known gene. [19] For known DNA sequences, restriction enzymes that cut the DNA on either side of the gene can be used. Gel electrophoresis then sorts the fragments according to length. [20]
Transfection is the process of deliberately introducing naked or purified nucleic acids into eukaryotic cells. [1] [2] It may also refer to other methods and cell types, although other terms are often preferred: "transformation" is typically used to describe non-viral DNA transfer in bacteria and non-animal eukaryotic cells, including plant cells.

In molecular cloning, a vector is any particle (e.g., plasmids, cosmids, Lambda phages) used as a vehicle to artificially carry a foreign nucleic sequence – usually DNA – into another cell, where it can be replicated and/or expressed. [1] A vector containing foreign DNA is termed recombinant DNA.
Bipartisan bills introduced in Congress Thursday would effectively ban a Chinese genomics firm from doing business in America. Intel officials have warned China is grabbing U.S. genetic info.
In bacterial conjugation, where DNA is transferred between bacteria through direct cell-to-cell contact, homologous recombination helps integrate foreign DNA into the host genome via the RecBCD pathway. The RecBCD enzyme promotes recombination after DNA is converted from single-strand DNA–in which form it originally enters the bacterium–to ...
