Natural transformation is a bacterial adaptation for DNA transfer that depends on the expression of numerous bacterial genes whose products appear to be responsible for this process. [20] [19] In general, transformation is a complex, energy-requiring developmental process. In order for a bacterium to bind, take up and recombine exogenous DNA ...
Genetic engineering. Recombinant DNA ( rDNA) molecules are DNA molecules formed by laboratory methods of genetic recombination (such as molecular cloning) that bring together genetic material from multiple sources, creating sequences that would not otherwise be found in the genome . Recombinant DNA is the general name for a piece of DNA that ...
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 ...
The purpose of a vector which transfers genetic information to another cell is typically to isolate, multiply, or express the insert in the target cell. All vectors may be used for cloning and are therefore cloning vectors , but there are also vectors designed specially for cloning, while others may be designed specifically for other purposes ...
The conservation-restoration of dye diffusion transfer prints is the process undertaken by conservator-restorers of caring for and maintaining dye diffusion transfer prints to preserve their form, and the information they contain. It covers the processes that can be taken by conservators, archivists, and other museum professionals.
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 ...
Conduction is the process by which heat is transferred from the hotter end to the colder end of an object. The ability of the object to conduct heat is known as its thermal conductivity, and is denoted k . Heat spontaneously flows along a temperature gradient (i.e. from a hotter body to a colder body). For example, heat is conducted from the ...
