Centrosome Structure and Centrioles — NEET Biology
📚 Practice ConceptCentrosome is an organelle usually containing two cylindrical structures called centrioles. They are surrounded by amorphous pericentriolar materials. Both the centrioles in a centrosome lie perpendicular to each other in which each has an organisation like the cartwheel. They are
Which of the following statements about the structure of centrioles in a centrosome is NOT correct? S1: A centrosome typically contains two cylindrical centrioles surrounded by amorphous pericentriolar materials. S2: The two centrioles in a centrosome are oriented parallel to each other. S3: Each centriole exhibits a cartwheel-like organisation with nine evenly spaced peripheral fibrils. S4: Each peripheral fibril in a centriole is composed of a doublet of tubulin protein. S5: The central proteinaceous hub of a centriole is connected to the peripheral fibrils by radial spokes.
