Often these cells are stem cells that are used for gene therapy. Chemical based methods uses natural or synthetic compounds to form particles that facilitate the transfer of genes into cells. [36] These synthetic vectors have the ability to bind DNA and accommodate large genetic transfers. [37]
The first attempt, an unsuccessful one, at gene therapy (as well as the first case of medical transfer of foreign genes into humans not counting organ transplantation) was performed by geneticist Martin Cline of the University of California, Los Angeles in California, United States on 10 July 1980.
DNA transposons, LTR retrotransposons, SINEs, and LINEs make up a majority of the human genome. Mobile genetic elements (MGEs), sometimes called selfish genetic elements, [1] are a type of genetic material that can move around within a genome, or that can be transferred from one species or replicon to another. MGEs are found in all organisms.
It's been reported that astronaut Scott Kelly no longer has the same DNA as his twin brother after spending a year in space.

In bacteria, spacer DNA sequences are only a few nucleotides long. In eukaryotes, they can be extensive and include repetitive DNA, comprising the majority of the DNA of the genome. [3] In ribosomal DNA, there are spacers within and between gene clusters, called internal transcribed spacer (ITS) and external transcribed spacers (ETS

Modifying a person's non-heritable DNA with the goal of improving one's medical condition is generally accepted and has a plethora of ethical protocols monitoring such procedures. [19] This includes modifications like organ donation, bone marrow transplants, and types of gene therapies, all of which consider cultural and religious values. [ 19 ]
