Liposomes and polymers can be used as vectors to deliver DNA into cultured animal cells. Positively charged liposomes bind with DNA, while polymers can designed that interact with DNA. [36] They form lipoplexes and polyplexes respectively, which are then up-taken by the cells. Other techniques include using electroporation and biolistics. [39]
Electroporation of DNA, RNA, or ribonucleocomplexes is a common technique, though it can result in harmful effects on the target cells. [79] Chemical transfection techniques utilizing lipids and peptides have also been used to introduce sgRNAs in complex with Cas9 into cells. [80] [81] Nanoparticle-based delivery has also been used for ...
The different generations of nucleases used for genome editing and the DNA repair pathways used to modify target DNA. Genome editing, or genome engineering, or gene editing, is a type of genetic engineering in which DNA is inserted, deleted, modified or replaced in the genome of a living organism.

Modern biology and biochemistry make intensive use of these techniques in recombinant DNA technology. Recombinant DNA is a man-made DNA sequence that has been assembled from other DNA sequences. They can be transformed into organisms in the form of plasmids or in the appropriate format, by using a viral vector. [159]
Diagram illustrating the development process of avian flu vaccine by reverse genetics techniques. Reverse genetics is a method in molecular genetics that is used to help understand the function(s) of a gene by analysing the phenotypic effects caused by genetically engineering specific nucleic acid sequences within the gene.
Gel electrophoresis is a process where an electric current is applied to DNA samples creating fragments that can be used for comparison between DNA samples. DNA is extracted. Isolation and amplification of DNA. DNA added to the gel wells. Electric current applied to the gel. DNA bands are separated by size. DNA bands are stained.
The first step in Gateway cloning is the preparation of a Gateway Entry clone. There are a few different ways to make entry clone. Gateway attB1 and attB2 sequences are added to the 5' and 3' end of a gene fragment, respectively, using gene-specific PCR primers and PCR amplification. The PCR amplification products are then mixed with a propriet
