What is nuclear organizing region or NOR?

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.

What are centrosomes also called?

Centrosomes are also called the microtubule-organizing center (MTOC) because they play a key role in organizing microtubules in animal cells during cell division.


What is the mtoc in the animal cell?

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.
