wil the recombinant die in the medium containg the resistant where the foreign gene got inserted?

Hi,

Your query seems to be little bit ambigous.

Although, we are providing you the answer, if query still persists then do get back to us.

Yes, recombinants will die if they are grown on the medium containing the same antibiotic, within the region of which the foreign DNA has been inserted in cloning vector while making recombinant DNA.

 This is because when Foreign DNA is inserted within antibiotic resistance gene in plasmid, then that antibiotic resistance gene will not be functional and the recombinants will not be able to grow on the medium containing the same antibiotic.

Let us understand this by an example

 Cloning vectors have been used to produce recombinant DNA. Cloning vector containing more than one cloning sites are used. Cloning vector contain selectable markergenes. Selectable marker(antibiotic resistance gene) is a gene that select by allowing transformed cells to survive on media contining toxic level of selective agent. ampR and tetR are called selectable markers because  if we ligate a foreign DNA at the restriction site of tetracycline resistant gene in a vector than they can be selected out from the non- recombinant ones. This is confirmed when the recombinants will grow in ampicillin containing media but not on that containing tetracycline (this happens because recombinant plasmid have lost tetracycline resistance due to insertion of foreign DNA).
