The basal body is comprised of which structural component(s) of flagella?

A basal body (synonymous with basal granule kinetosome and in older cytological literature with blepharoplast) is a protein structure found at the base of a eukaryotic undulipodium (cilium or flagellum). It is formed from a centriole and several additional protein structures and is essentially a modified centriole. The basal body serves as a nucleation site for the growth of the axoneme microtubul…

A basal body (synonymous with basal granule kinetosome and in older cytological literature with blepharoplast) is a protein structure found at the base of a eukaryotic undulipodium (cilium or flagellum). It is formed from a centriole and several additional protein structures and is essentially a modified centriole. The basal body serves as a nucleation site for the growth of the axoneme microtubules. Centrioles from which basal bodies are derived act as anchoring sites for proteins that in turn anchor microtubules and are known as the microtubule organizing center (MTOC). These microtubules provide structure and facilitate movement of vesicles and organelles within many eukaryotic cells.

Cilia and basal bodies form during quiescence or the G1 phase of the cell cycle . Before the cell enters G1 phase i.e. before the formation of the cilium the mother centriole serves as a component of the centrosome .

Cilia and basal bodies form during quiescence or the G1 phase of the cell cycle . Before the cell enters G1 phase i.e. before the formation of the cilium the mother centriole serves as a component of the centrosome . In cells that are destined to have only one primary cilium the mother centriole differentiates into the basal body upon entry into G1 or quiescence. Thus the basal body in such a cell is derived from the centriole. The basal body differs from the mother centriole in at least 2 aspects. First basal bodies have basal feet which are anchored to cytoplasmic microtubules and are necessary for polarized alignment of the cilium. Second basal bodies have pinwheel-shaped transition fibers that originate from the appendages of mother centriole. In multiciliated cells however in many cases basal bodies are no...
