This process of the second bacterial cell taking up new genetic material is called transformation. In molecular biology and genetics, transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from its surroundings through the cell membrane (s).
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 ...
Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
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 undergoing bacterial ...
SDS-PAGE is an electrophoresis method that allows protein separation by mass. The medium (also referred to as ′matrix′) is a polyacrylamide-based discontinuous gel. The polyacrylamide-gel is typically sandwiched between two glass plates in a slab gel. Although tube gels (in glass cylinders) were used historically, they were rapidly made ...

Spiegelman's Monster. Spiegelman's Monster is an RNA chain of only 218 nucleotides that is able to be reproduced by the RNA replication enzyme RNA-dependent RNA polymerase, also called RNA replicase. It is named after its creator, Sol Spiegelman, of the University of Illinois at Urbana-Champaign who first described it in 1965.
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.
