NCBI Organism Classification
Notophthalmus viridescens
Biological Process
ribosomal RNA transcription
Cellular Component
nuclear chromosome
Amphibian oocytes have many copies of rRNA genes that are actively transcribed. Newt ocyte nuclei were dissected, allowed to swell in a low ionic strength high pH buffer, centrifuged through a sucros...

Gallus gallus gallus
Biological Process
chromatin assembly
Cellular Component
chromosome, telomeric region
Telomeres isolated from chicken erythrocyte nuclei following restriction endonuclease treatment, and imaged by transmission EM after uranyl acetate negative staining. Sample was also labeled for the t...

Necturus maculosus
Biological Process
chromatin assembly
Cellular Component
nuclear chromatin
X-ray scattering shows that the nucleated erythrocytes of the amphibian Necturus maculosus (Mud Puppy) contain more ordered chromatin than most nuclei. Here, fibers isolated from these nuclei have bee...
