mini nucleolus like region with a rDNA containing chromosome (13, 14, 15, 21 or 22) which forms during early G1 phase.

The outside of the nucleolus is called the nucleolar periphery or nucleolar cortex. It is involved in interactions with other cellular structures and processes, such as the nuclear envelope and ribosomal RNA processing.
Microtubules radiate from the microtubule-organizing center (MTOC) located near the center of the cell. They play a key role in various cellular processes, including cell division and intracellular transport.
Centrosomes produce Microtubules. This is the reason why they are also called "Microtubule Organizing Center". They help in regulation of cell cycle.
A nuclear organizing region (NOR) refers to a specific chromosomal region that is associated with the formation of nucleoli in the nucleus of eukaryotic cells. NORs contain ribosomal RNA (rRNA) genes and are involved in the transcription of rRNA, which is essential for ribosome assembly. These regions play a crucial role in organizing and regulating the synthesis of ribosomal components, thus contributing to protein synthesis in the cell. Additionally, NORs are often found on the nucleolar organizer chromosomes, which are essential for nucleolar function.

Centrosomes are also called the microtubule-organizing center (MTOC) because they play a key role in organizing microtubules in animal cells during cell division.
The microtubule-organizing center (MTOC) in animal cells is called the centrosome, which is located near the nucleus. It is responsible for organizing and anchoring microtubules during cell division and maintaining cell shape and polarity. The centrosome consists of a pair of centrioles surrounded by pericentriolar material.
