nucleus
3 -Prophase I of meiosis, zygotene substage in a diploid lily pollen mother cell. The nucleoli have fused into one large nucleulus which is disc shaped and pressed up against the nuclear envelope (ri...

synaptonemal complex
Nucleus of a plant cell showing synaptonemal complex, a ladder- like protein structure that forms between pairing chromosomes during meiosis (the cell division required for reproduction). This image w...

meiosis
Cellular Component
spindle
The movie shows several sequences showing changes in birefringence in oocytes of the marine annelid Chaetopteris that had formed meiotic spindles before exposure to centrifugal force in the Centrifuge...

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
male meiosis chromosome segregation
Cellular Component
cytoskeleton
The events of meiosis I and II in a living insect spermatocyte beginning with the breakdown of the nuclear envelope at diakinesis through to the completion of cytokinesis. Testes from the Crane fly N...

spindle assembly involved in female meiosis
Cellular Component
Egg extract
Movie shows spindle assembly around DNA-beads in a Xenopus laevis egg extract. DNA beads are autofluorescent, and spindle is formed from exogenous X-rhodamine-labeled tubulin. By the end of the movie...

spindle assembly involved in male meiosis I
Cellular Component
cytoskeleton
The events of meiosis I in a living insect spermatocyte beginning at metaphase with bivalents at the spindle equator, followed by anaphase onset, chromosome segregation and the start of cytokinesis. T...

meiotic metaphase II
Cellular Component
spindle microtubule
Frog (Xenopus laevis) egg arrested in metaphase of mitosis. Note the tiny metaphase spindle on the top left of the egg. Eggs were fixed in 90% MeOH; 10% (H20 500mM EGTA) and stained for DNA with YoP...
