There are many different reasons for
gene transfer: for example, attempting to treat disease by supplying patients with therapeutic genes. There are also many possible ways to
transfer genes.
Full article >>>Phylogenetic analyses indicate that
Drosophila P
elements have been
transferred horizontally (Ref).
Horizontal
transfer is also called
lateral gene transfer and may account for 10 to 50% of all the genes in a
bacterial or archaeal
genome.
Full article >>>Gene transferOrganisms can generally inherit genes in two ways. 1. By
speciation (vertical
gene transfer). Meaning from parent to
offspring. 2. By Horizontal or
lateral gene transfer.

cell to another brought about by a
virus. The phenomenon was first described by Lederberg, Lederberg, Zinder and Lively (1952) with reference to Salmonella typhimurium, ...
Full article >>>Gene transfer agent
A
phage-like agent from Rhodobacter capsulates
species which can
transfer
DNA from the donor
host to recipient
cells.

DNA into and
organism's

Full article >>>Lateral Gene TransferBacteria possess several methods for
lateral gene transfer (also called
horizontal gene transfer), the
transmission of genes between individual
cells.
Full article >>>Horizontal gene transfer is invoked to explain how there is often extreme
similarity between small portions of the
genomes of two
organisms that are otherwise very distantly related.
Horizontal gene transfer seems to be common among many
microbes.

gene transfer.
Complementary DNA molecules are adsorbed to gold particles and shot by a pressure gas jet into
tissues or
culture cells.

Full article >>>By their very nature,
phylogenetic trees hide any
hybridization and
lateral gene transfer (Woese 2002) that may have taken place. For these reasons, the proposed PhyloCode (see External Link below) does not assume a tree structure.
Full article >>>reticulation -- Joining of separate
lineages on a
phylogenetic tree, generally through
hybridization or through
lateral gene transfer. Fairly common in certain land
plant clades; reticulation is thought to be rare among
metazoans.
Full article >>>Transgenic pigs have also been produced by fertilizing normal eggs with
sperm cells that have incorporated foreign
DNA. This procedure, called
sperm-mediated
gene transfer (SMGT) may someday be able to produce
transgenic pigs that can serve as a ...

Transmissible
plasmid (
episome) in
bacteria (such as E. coli) that acts as a sex factor. It is a circular
DNA about 94 kb
