In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells, but...

called connecting piece contains one typical centriole and one atypical centriole such as the proximal centriole-like. The midpiece has a central filamentous...

in certain fly and flatworm species. Centrosomes are composed of two centrioles arranged at right angles to each other, and surrounded by a dense, highly...

The proximal centriole-like or PCL is an atypical type of centriole found in the sperm cells of insects. The PCL name is due to some similarity to the...

in 1880. It is formed from a centriole and several additional protein structures, and is, essentially, a modified centriole. The basal body serves as a...

has a proximal centriole parallel to the base of the nucleus and distal centriole perpendicular to the previous one. The proximal centriole is present also...

sperm cells have atypical centrioles. One of the two sperm centrioles of fruit fly exhibit the retention of "juvenile" centriole structure, which can be...

is composed of two orthogonal cylindrical protein assemblies, called centrioles, which are surrounded by a protein dense amorphous cloud of pericentriolar...

is a more or less circular cell containing a nucleus, Golgi apparatus, centriole and mitochondria; by the end of the process, it has radically transformed...

attached at its base to a centriole known as the distal centriole and acts as a basal body. In most animals, this distal centriole act as a shock absorber...

(such as an epithelial cell of respiratory tract) that produces multiple centrioles. Most cells in human body possess one primary cilium, a relatively small...

which makes up the part of the animal centrosome that surrounds the two centrioles. The PCM contains proteins responsible for microtubule nucleation and...

centrosome is made up of two cylinders called centrioles, oriented at right angles to each other. The centriole is formed from 9 main microtubules, each having...

through the ER and the Golgi apparatus. Centrosomes are composed of two centrioles which lie perpendicular to each other in which each has an organization...

mitotic spindle poles. Centrioles can act as markers for MTOCs in the cell. If they are freely distributed in the cytoplasm, centrioles can gather during differentiation...

microtubules on one of the centrioles, which turns into basal body. These microtubules form an axoneme. Later the centriole is modified in the process...

CNTROB gene. It is a centriole-associated protein that asymmetrically localizes to the daughter centriole, and is required for centriole duplication and cytokinesis...

snails. Some organelles also have structural inheritance, such as the centriole, and the cell itself (defined by the plasma membrane) may also be an example...
