Chaetopterus sp. 1 Woods Hole MA
Biological Process
meiosis
Cellular Component
spindle
This is one of 4 grouped time lapse movies (CIL 11958-11962) revealing the responses of a meiotic oocyte spindle to various forms of micromanipulation by a glass microneedle. The needle is inserted, ...

Nephrotoma suturalis
Biological Process
spindle assembly involved in male meiosis II
Cellular Component
cytoskeleton
The events of meiosis I in a living insect spermatocyte beginning at metaphase with meiotic bivalents at the spindle equator followed by anaphase , segregation of bivalents to the spindle poles and t...
