Things You Must Know About Recombinant Protein

The transduction process is not a novel one. It’s a phenomena in which DNA from one bacterium is transferred to another bacterium via a viral vector. Transduction is also defined as the process through which a virus introduces foreign DNA from one cell into another cell. This is a relatively common method used by molecular biologists to introduce a foreign gene into the host’s DNA. Norton Zinder and Joshua Lederberg performed the initial transduction experiments in 1951 at the University of Wisconsin-Madison. Bacteriophages are virus-like viruses that infect bacteria. When such bacteriophages infect a bacterial cell, their primary role is to take over replication, transcription, and translation in the host cell for their own purpose, resulting in a large number of virions (complete viral particles) containing DNA or RNA and a protein coat. Transduction can start in either a lytic or a lysogenic cycle. The bacteriophage’s chromosome is absorbed into the bacterial chromosome, where it can remain inactive for thousands of generations if the lysogenic cycle is used. If the lysogen is produced by another method, such as UV radiation, the phage chromosome is deleted from the bacterial genome, triggering the lytic cycle, which ends in cell lysis and phage particle release. The lytic cycle is in charge of producing additional phage particles, which are released when the host cell is lysed. Check his comment is here.

Small bits of bacterial DNA, as well as small fragments of bacteriophage genome, may become condensed together into the bacteriophage genome due to the low dependability of viral DNA packaging. Some phage genes are left behind in the bacterial chromosome during the packing process. There are three forms of recombination mechanisms that might result in the incorporation of bacterial DNA into viral DNA, resulting in two different types of transduction procedures. These transductions are both universal and specialised. Recombination or careful packing can be used to achieve generalised transduction. The lytic cycle will be followed if the bacteriophage, after entering the bacterial cell, takes charge of the host cell’s machinery for creating viral particles, but if the bacterial chromosomal DNA is accidentally introduced into the viral capsid, the generalised transduction cycle will begin. When a virus uses careful packaging to replicate, it seeks to fill its nucleocapsid with genetic material.
