Cell cycle parameters of diploid and triploid V79 cells
| Diploid | Triploid | |||||
|---|---|---|---|---|---|---|
| Doubling time (h) | 20.4 | 20.4 | ||||
| Phase | G1 | S | G2/M | G1 | S | G2/M |
| Fraction* | 0.508 (0.485) | 0.375 (0.359) | 0.116 (0.111) | 0.480 (0.388) | 0.415 (0.336) | 0.105 (0.085) |
| Duration (h)** | 8.6 | 8.5 | 3.2 | 8.1 | 9.4 | 2.9 |
*
Phase fractions of diploid and triploid cells were determined omitting those for other ploidies in the V79 cell population. Numbers in parentheses represent the fraction in the total cell population.
**
Phase duration was calculated through conventional equations ( Watanabe & Okada 1967 ) using doubling time instead of cycle time.
