Table 2. The concentration of tRNA during the cell cycle in the yeast S. cerevisiae.

Time points (min)	tRNA concentration (mg/ml)	Estimated cell-cycle phase
The measurements were performed using cells synchronized in M phase and then released. Over the 4-h time course the cells started in and subsequently returned to M phase. Accordingly, the tRNA concentrations measured at the beginning and end of the experiment are consistent.
0	10.0	Synchronized in M phase
30	7.8	M
60	14.9	G1
90	13.7	G1
120	4.1	G1
150	10.8	G1
180	7.9	S
210	11.5	S
240	21.3	G2
270	21.5	G2
300	9.7	M
