Calculate the number of times the DNA of a modern E. coli cell has been copied accurately since its earliest bacterial precursor cell arose about 3.5 billion years ago. Assume for simplicity that over this time period, E. coli has undergone, on average, one cell division every 12 hours (this is an overestimate for modern bacteria, but probably an underestimate for ancient bacteria).

The conversion of ammonium to amino acids requires two enzymes such as GS and GOGAT,
a) High levels of light and carbohydrate—conditions that stimulate plastid GS and Fd-GOGAT
b) Conditions of ample energy inhibit GS and GOGAT
c) The stimulation of GS and GOGAT, they favor nitrogen assimilation into glutamine and glutamate, compounds that are rich in carbon and participate in the synthesis of new plant materials
d) In energy-limited conditions inhibit GS and GOGAT
Which of the following statements about GS and GOGAT is correct?
