The diagram shows a bacterial cell containing a plasmid (small circular piece of DNA) that has been altered in the laboratory to produce recombinant DNA.
_____ 1. Because bacterial plasmids can incorporate gene segments from a variety of living things, one can assume that …
a. bacterial chromosomes are identical to other types of chromosomes
b. the DNA building blocks in all living things function similarly
c. bacteria can be turned into other species of living things
d. all bacteria pose a health threat to humans and other animals
_____ 2. Once the foreign piece of DNA is incorporated into the plasmid, the bacterial cell will “read” the gene sequence and, possibly, manufacture new substances as a result. What two processes will control these events?
a. restriction and magnification
b. replication and mutation
c. recombination and replacement
d. transcription and translation
