a. use a microscope to observe cell division to determine the structure of operons.
b. test the response of e. coli to a variety of chemicals to determine the number of operons that are present.
c. insert the operons from one organism into another to determine the mechanism of operon expression.
d. read the genome sequence to determine the quantity and organization of operons.

D. Read the genome sequence to determine the quantity and organization of operons.

halogen, any of the six nonmetallic elements that constitute group 17 (group viia) of the periodic table. the halogen elements are fluorine (f), chlorine (cl), bromine (br), iodine (i), astatine (at), and tennessine (ts).

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude
