Concept explainers
(a) Interpretation:
Explain why the recombinant plasmid is treated with EcoRI to determine its size.
Concept introduction:
Plasmids are circular and small double stranded DNA and is different from the DNA of the cell's chromosome. Plasmids are naturally found in bacterial calls and some Eukaryotes. They act as a tool for the purpose of cloning, transfer and gene manipulation. Plasmids used for experimental purposes are termed as vectors. The genes or DNA fragments can be inserted into the plasmid vector which thus forms recombinant plasmid.
(b) Interpretation:
The discrepancy between the size of the recombinant molecule and the sum of the size of the HindIII cleavage fragments should be explained.

(c) Interpretation:
The diagram of the recombinant showing the locations of the HindIII cleavage sites should be drawn.
