NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
nuclear pore distribution
Cellular Component
macronucleus
Grazing thin section through the nuclear envelope of a macronucleus. Nuclear pores are packed so tightly that they often form a hexagonal array with 6 pores surrounding a central pore. The pores often...

Paramecium multimicronucleatum
Biological Process
macronucleus organization
Cellular Component
macronucleus
The macronucleus is the largest organelle in the P. multimicronucleatum cell and can measure 35µm long by 12µm wide. A small fraction of a macronucleus is seen in this micrograph. The chromatin appe...

Tetrahymena pyriformis
Biological Process
macronucleus organization
Cellular Component
macronucleus
High resolution view of the nuclear envelope of both the macronucleus, seen here, and the micronucleus consists of 2 membranes containing numerous perforations called pores. Proteins are imported thro...

Drosophila melanogaster
Biological Process
mitotic nuclear envelope disassembly
Cellular Component
nucleus
This Drosophila melanogaster early embryo (cycles 10-12) was injected with a fluorescent protein containing a nuclear localization signal (GFP-NLS). Proteins that contain a NLS are recognized by impor...

Biological Process
nuclear pore complex assembly
Cellular Component
nuclear pore
HeLa cells were processed for indirect immunofluorescence with antibodies to two nuclear pore components, ELYS (embryonic large protein derived from yolk sac) and mAb414 against the FG nucleoporins. B...
