Which best describes the process of bacterial transformation?

Bacterial transformation is a process of horizontal gene transfer by which some bacteria take up foreign genetic material (naked DNA) from the environment. The process of gene transfer by transformation does not require a living donor cell but only requires the presence of persistent DNA in the environment.

Which best describes conjugation in bacteria answers?

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. This takes place through a pilus.

What is an example of bacterial transduction?

Transduction occurs when foreign DNA or RNA is introduced into bacterial or eukaryotic cells via a virus or viral vector. One example are bacteriophages that attach to bacterial membranes and inject their genetic material into the cell.

Which one of the following is an example of bacterial transformation?

Bacterial transformation is used: To make multiple copies of DNA, called DNA cloning. To make large amounts of specific human proteins, for example, human insulin, which can be used to treat people with Type I diabetes. To genetically modify a bacterium or other cell.

What is the purpose of bacterial transformation?

Bacterial transformation is a key step in molecular cloning, the goal of which is to produce multiple copies of a recombinant DNA molecule. Prior steps for creating recombinant plasmids are described in traditional cloning basics and involve insertion of a DNA sequence of interest into a vector backbone.

What are the two types of transduction?

There are two types of transduction: generalized and specialized. In generalized transduction, the bacteriophages can pick up any portion of the host’s genome. In contrast, with specialized transduction, the bacteriophages pick up only specific portions of the host’s DNA.

What is the process of transduction in bacteria?

Transduction, a process of genetic recombination in bacteria in which genes from a host cell (a bacterium) are incorporated into the genome of a bacterial virus (bacteriophage) and then carried to another host cell when the bacteriophage initiates another cycle of infection.
