Assume that you are trying to insert a gene into a plasmid andsomeone gives you a DNA sample cut with restriction enzyme X. Thegene you wish to insert from the given sample has sites on bothends for cutting by restriction enzyme Y. You have a plasmid with asingle site for Y, but not for X. Your strategy should be to

cut the plasmid with restriction enzyme X and insert thefragments cut with Y into the plasmid.
cut the plasmid with enzyme X and then insert the gene into theplasmid.
cut the DNA again with restriction enzyme Y and insert thesefragments into the plasmid cut with the same enzyme.
cut the plasmid twice with restriction enzyme Y and ligate thetwo fragments onto the ends of the human DNA fragments cut withrestriction enzyme X.
insert the fragments cut with X directly into the plasmidwithout cutting the plasmid.

b) Vectored cloning is superior to PCR cloning of a gene in terms of __________.

A. time it takes to finish cloning

B. size of DNA that can be cloned

C. amounts of cloned DNA that can be generated

D. ease of isolation of the DNA fragment to be cloned

c) Which of the following is a recombinant DNA molecule?

B. Fish insulin gene, PCR amplified and then cut by EcoRI

C. pUC18 DNA and fish insulin DNA ligated by a DNA liagse

D. pUC DNA and fish insulin gene DNA, both cut by EcoRI and mixed

d) You may insert a foreign DNA fragment inside a live cell using each of the following methods except________.

A. inject the DNA inside the cell

B. mix the DNA with the cell and freeze the mixture in liquid nitrogen

C. mix DNA with the cell and momentarily heat the cell then cool down

D. mix DNA with the cell and momentarily zap the cells with a high voltage

E. cover the DNA in a lipid micelle and mix the micelle with the cell

e) Technically, the ampicillin resistance gene is a selectable marker gene but the beta lacZ gene or the green fluorescent protein (GFP) gene is a reporter gene of a cloning vector. What is the difference between a selectable marker and a reporter gene?

A. A selectable marker is a bacterial gene, a reporter gene is a eukaryotic gene

B. Marker genes are used in bacterial system; reporter genes are used in eukaryotic system.

C. The selectable markers help eliminate cells lacking the maker, reporter genes do not offer this option.
