TABLE 3:
Summary of the effect of varying powers in the trap on kinetochore movement when applied to the kinetochore in Mesostoma spermatocytes.
| Trapping kinetochores in M. ehrenbergii spermatocytes | ||||||||
|---|---|---|---|---|---|---|---|---|
| Power at the focus (26% of power at back focal plane) (mW) | Stops movement and recovers | Stops movement and no recovery | Decreases amplitude | No effect | Total | Stopped kinetochore movement | Decreased amplitude | Stopped movement or decreased amplitude |
