Transduction
Transduction involves the transfer of bacterial DNA from one bacterium to another using a bacteriophage as a vector, whereas normal bacteriophage infection results in the lysis of the host bacterium after replication. Transduction is a form of horizontal gene transfer that can transfer genetic material such as antibiotic resistance genes between bacteria, while normal bacteriophage infection primarily involves viral replication and host cell lysis.
The transformation of a prokaryotic cell typically involves uptake of naked DNA from the environment, followed by incorporation into the bacterial chromosome through recombination. In contrast, transformation of a eukaryotic cell often involves more complex processes, such as endocytosis of DNA fragments packaged in lipid vesicles or integration through viral vectors. Additionally, eukaryotic transformation is commonly used for genetic engineering in higher organisms, while prokaryotic transformation is most frequently studied in bacteria.
Yes, RNA viruses can facilitate transduction by integrating their genetic material into the host cell's genome, leading to the expression of viral genes. This process can help deliver therapeutic genes to target cells for gene therapy applications.
What are the different viral families? What are their genomescreated from? Are they naked?
Bacteria can gain genetic diversity through transformation, which involves taking up DNA from the environment; conjugation, where genetic material is transferred directly between cells via a pilus; and transduction, where genetic material is transferred by a virus.
Transduction
It is called Transduction.
Abortive transduction occurs when a bacteriophage injects its genetic material into a bacterial cell, but the viral DNA fails to replicate and instead integrates into the host bacterial genome. This can result in a mixed bacterial population with some cells acquiring new genetic traits from the phage.
The process is called transduction, where viral DNA is transferred into a bacterial cell, integrated into the bacterial chromosome, and expressed by the bacterial cell.
Transduction is the process by which a cell converts environmental signals into electrical or chemical signals that can be interpreted by the cell. It is a key mechanism in cell signaling pathways that allow cells to respond to their external environment.
Generalized transduction can transfer any bacterial gene, while specialized transduction transfers only specific genes located near the integrated prophage site. Generalized transduction is caused by a lytic phage, while specialized transduction is caused by a lysogenic phage reactivating and entering the lytic cycle.

Transformation: introducing naked DNA into bacterial cells through heat shock or electroporation. Transduction: using a viral vector to deliver DNA into cells. Conjugation: direct transfer of genetic material between bacterial cells through a conjugative bridge. Lipofection: using lipid-based molecules to facilitate the entry of DNA into eukaryotic cells. Electroporation: applying an electric field to create transient pores in cell membranes for DNA uptake.
