👉 Kinetosome, also known as nucleolus or nucleolus of ribosomes, is a small organelle located within the cytoplasm of a cell. It is composed primarily of the nuclear envelope and consists of two sets of proteins called 'kinases'. The kinases in the kinetosome catalyze reactions that are crucial for the assembly and function of the ribosome. These reactions include:
1.
Poly-A tailing
