In pBR 322, how many recognition sites are present ?

In pBR 322, recognition segqences, that are present on the same type of selectable marker

pBR 322, BR stands for

How many sites are present on the ribosome?

Assertion : E.coli having pBR322 with DNA insert at BamH 1 site cannot grow in medium containing tetracycline. Reson: Recognition site for BamH 1 is present in tetR region of pBR322.

Assertion: E. coli having pBR322 with DNA insert at BamHI site cannot grow in medium containing tetracycline. Reason: Recognition site for Bam HI is present in "tet"^(R) region of pBR322.

In pBR 322 amp^(R) and "tet"^(R) gene are present. When we ligate a foreign DNA at Pst-I site, then recombinant plasmids will lose the resistance to the

E. coli cloning vector pBR322 contains restriction sites in the region of amp^( R) , tet^(R ) genes that codes for the

E. coli cloning vector pBR322 contains restriction sites in the region of amp^( R) , tet^(R ) genes that codes for the

Assertion : E.coli having pBR322 with DNA insert at BamHI site cannot grow in medium containing tetracyline. Reason : Recoginition site for BamHI is present in ter^(R) region of pBR22.
