Transduction is the process by which foreign DNA is introduced into a cell by a virus or viral vector. [ 1] An example is the viral transfer of DNA from one bacterium to another and hence an example of horizontal gene transfer. [ 2] Transduction does not require physical contact between the cell donating the DNA and the cell receiving the DNA ...
Bacterial conjugation. Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. [ 1] This takes place through a pilus. [ 2][full citation needed] It is a parasexual mode of reproduction in bacteria. A micrograph displaying Escherichia coli ...
Horizontal gene transfer ( HGT) or lateral gene transfer ( LGT) [ 1][ 2][ 3] is the movement of genetic material between organisms other than by the ("vertical") transmission of DNA from parent to offspring ( reproduction ). [ 4] HGT is an important factor in the evolution of many organisms. [ 5][ 6] HGT is influencing scientific understanding ...
Paper marbling is a method of aqueous surface design, which can produce patterns similar to smooth marble or other kinds of stone. [ 1] The patterns are the result of color floated on either plain water or a viscous solution known as size, and then carefully transferred to an absorbent surface, such as paper or fabric.

Genetics is the study of genes, genetic variation, and heredity in organisms. [ 1][ 2][ 3] It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically.

A high-frequency recombination cell (Hfr cell) (also called an Hfr strain) is a bacterium with a conjugative plasmid (for example, the F-factor) integrated into its chromosomal DNA. The integration of the plasmid into the cell's chromosome is through homologous recombination. A conjugative plasmid capable of chromosome integration is also ...
