The gene must then be isolated and incorporated, along with other genetic elements, into a suitable vector. This vector is then used to insert the gene into the host genome, creating a transgenic or edited organism. The ability to genetically engineer organisms is built on years of research and discovery on gene function and manipulation.
In biology, a marker gene may have several meanings. In nuclear biology and molecular biology, a marker gene is a gene used to determine if a nucleic acid sequence has been successfully inserted into an organism's DNA. In particular, there are two sub-types of these marker genes: a selectable marker and a marker for screening.
The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. [1] DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other contaminants, and ...
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. Unlike early genetic engineering techniques that randomly insert genetic material into a host genome, genome editing targets the insertions to site-specific locations.

This design enables efficient identification of recombinant plasmids, as the insertion of foreign DNA into the MCS disrupts the marker gene, allowing for blue-white screening or other selection methods. [6] In expression vectors, MCSs are positioned between a promoter and a terminator to regulate gene expression. The upstream promoter can be ...
The safety of gene therapy treatment is of utmost concern, especially during clinical trials when off-target modifications can block the further development of a candidate product. [57] Perhaps the most well-known example of modern gene therapy is CAR-T therapy, which is used for the treatment of B-cell lymphoma.
CCL2 is primarily secreted by monocytes, macrophages and dendritic cells. Platelet derived growth factor is a major inducer of CCL2 gene. CCR2 and CCR4 are two cell surface receptors that bind CCL2. [14] CCL2 exhibits a chemotactic activity for monocytes and basophils. However, it does not attract neutrophils or eosinophils.
