TRANSGENIC BACTERIA ARE OTHERWISE CALLED GENETICALLY MODIFIED BACTERIA. THEY CONTAIN A NOVEL GENE FROM OTHER SOURCE WHICH BECOMES PART OF THEIR NATIVE GENOME ARCHITECTURE OR AS TRANSIENT GENE MAINTAINED ON PLASMIDS.
TRANGENESIS IN BACTERIA CAN EITHER BE NATURAL OR LABORATORY MADE.
EVOLUTIONARILY SPEAKING FOR EXAMPLE, Escherichia sps are all natural transgenic bacteria, due to the fact that bacteria can undergo transformation by picking up any available DNA in its sorrounding and this is seen when comparing strains of Ecoli such 015:H7 strain (it contains pathogenic gene which is its virulence factor) as compared to some other strains of Ecoli which are non pathogenic.
laboratory made trangenic bateria is E coli BL21 (DE3), this bacteria is genetically modified to carry out gene expression at a very high rate while E coli BL21 is genetically modified to only amplify a cloned gene at a faster rate.
Transgenic bacteria contains foreign gene which is inserted into the genome of that bacteria….. The insertion usually is done through a plasmid (it is a self replicating part which undergo replication when introduce d into other organism) eg BT bacillus thurigness…
Thanks, Devansh for A2A,
Transgenic or genetically modified.
Transgenic bacteria are the bacteria which contains the foreign gene of interest in their genome.
Because this process involves the transfer of genes, GMOs are also known as “transgenic” organisms.
The most common example of transgenic bacteria is E.coli. modified to produce synthetic human insulin.
