The reason that a recA protein mutation in Escherichia coli make it a better host for the propagation of recombinant plasmid DNA (Deoxyribose nucleic acid ). Introduction: Restriction endonucleases which are also called molecular scissors are the enzymes that are used in molecular biology for the formation of the recombinant molecule. Plasmid vectors act as the carriers of foreign information that has to be incorporated into a recombinant molecule.

Cloning vectors for E Coli. For each of the following items, describe what it is explain the necessity for each in cloning plasmids that are used for the expression (production) of protein. what would happen if this element was omitted? The Multiple Cloning Site (MCS) Origin of replication – (AmpR) antibiotic resistance gene – T7 promoter - T7 termination site- lac I gene

please help me with this question. As this is a non-directional cloning, recombinant plasmids can contain an insert ligated into the vector in two different orientations. Provide two diagrams to illustrate the two potential recombinant plasmids, with the inserts ligated in opposite orientations. Include all RE sites and distances between sites on the diagram.
