|
|
A specific gene in a DNA sequence is identified.

|
The DNA segment is combined into a plasmid.

|
|
The DNA segment to be inserted is isolated.

Detailed explanation-1: -Insertion of recombinant DNA into the host The host is the final tool of rDNA technology, which consumes the vector engineered with the desired DNA with the aid of the enzymes. Insertion of the desired recombinant DNA into the host organism can be achieved in various ways.
Detailed explanation-2: -The final step in the construction of a recombinant plasmid is connecting the insert DNA (gene or fragment of interest) into a compatibly digested vector backbone. This is accomplished by covalently connecting the sugar backbone of the two DNA fragments.
Detailed explanation-3: -Transfer of this DNA to another cell is referred to as transduction. Transferred DNA once inside the infected bacterium can either exist as transient extrachromosomal DNA, like a plasmid, or it can integrate into the host bacterium’s genome through homologous or site directed recombination.
