NCBI Organism Classification
Patiria miniata
Biological Process
fertilization
Cellular Component
nuclear chromatin
Phosphorus has a characteristic electron energy loss with an edge at 160 eV. The Zeiss 902 electron microscope permits images to be recorded at different energy losses which can be digitized and proce...

Halteria grandinella
Biological Process
DNA replication checkpoint
Cellular Component
macronucleus
The DNA replication band in macronucleus of Halteria. Like hypotrichs the macronucleus of this oligotrich has a DNA replication band where DNA is synthesized. The nucleolus is evident. TEM taken on 3/...

nuclear chromatin
Transmission electron micrographs. The upper panel shows a section through a frog nucleated erythrocyte. The nucleus is largely filled with heterochromatin which appears to have a fibro-granular stru...

nucleus organization
Cellular Component
nucleolar chromatin
Transmission electron micrograph of transcription of tandemly arranged ribosomal RNA genes. Amphibian oocyte nuclei contain numerous extra-chromosomal nucleoli, each of which contains a tandem array o...

male germ cell nucleus
Transmission electron micrograph of unstained cryo-section of a sperm cell of the starfish Patiria miniata. Echinoderm sperm nuclei are unusual in that chromatin fibers are clearly seen, allowing the...

micronucleus organization
Cellular Component
micronucleus
Like other ciliates two types of nuclei are present. A germinative micronucleus and a RNA-producing macronucleus. Both have nuclear envelopes with pores and both have ribosomes attached to their outer...
