Question

How could you compare the original plasmid and the engineered plasmid in the lab using restriction digestion and gel electrophoresis?

Answer 1

A plasmid is a small, circular, doubled-stranded DNA molecule that is distinct from a cell's  chromosomal DNA. They are naturally exist in bacterial cells and they also occur in some eukaryotes. While engineered plasmid has an origined of replications. I hope you are satisfied with my answer and feel free to ask for more 

Answer 2

You could match the original plasmid and the superintended plasmid in the lab by restriction digestion and gel electrophoresis because of the restriction digestion benefits by examining and concocting DNA since you will be capable to see the distinction between the original and engineered plasmid due to structural differences. Moreover, gel electrophoresis is capable to segregate DNA from RNA and hence, making you observe some inconsistencies between the primary plasmid and the engineered plasmid.

Explanation:

You could match the original plasmid and the engineered plasmid in the lab by examining the number of restriction sites for the specific enzyme before and after modification gained after the method of gel electrophoresis. When we cut up the DNA, we filed them by length like the gel electrophoresis would.
