Suppose a restriction enzyme recognizes the six-base sequencein a double strand of DNA. Between which two nucleotides on each strand would the enzyme have to cut to produce a fragment with sticky ends that are four bases long?
Suppose a bacterial culture were mixed with recombinant plasmids containing a gene for resistance to penicillin. The bacterial culture was then treated with penicillin. Which of the following statements is NOT true?
Exposing a population of plants to radiation or certain chemicals can increase the frequency of mutations that occur within the population. _________________________
During DNA sequencing, if all the bands on an electrophoresis gel are the same color, the single-stranded DNA sample consisted of one kind of fragment. _________________________
Bacterial cells that have been transformed with a plasmid that carries a genetic marker for resistance to the antibiotic tetracycline will not survive in a culture treated with tetracycline. _________________________
The fact that human genes inserted into bacteria produce proteins shows that the basic mechanisms of gene expression are different in bacteria and humans. _________________________
To produce Dolly, Ian Wilmut removed the nucleus from a sheep’s body cell and fused it with a cell taken from another adult. _________________________

DNA samples taken from Dolly and the sheep that donated the body cell would show ____________________ patterns of bands on an electrophoresis gel.
Suppose you want to produce a new animal breed or plant species with certain desirable traits. Write a brief description of the traits you would want the organism to have. Then, explain how you would use selective breeding techniques to produce an organism with those traits.
Suppose you are a scientist trying to help people who cannot produce an enzyme needed for proper digestion. How could you use genetic engineering techniques to make transformed bacteria that produce the enzyme?
