Which organelle has a 9 0 pattern of microtubules and is associated with the formtation of basal bodies?
This is not quite an organelle, but cilia located in the nodal region of embryos have a 9 + 0 pattern. The cilia function to create a flow of morphogens that allow for left right determination in the organism.

Which of the 9 2 arrangement of microtubules consists of nine doublets of microtubules surrounding a pair of single macrotubules?
The arrangement of microtubules described consists of nine doublets of microtubules surrounding a pair of single microtubules in the center. This arrangement is known as the "9+2" structure, found in eukaryotic flagella and cilia. It provides structural support and aids in the movement of these cellular structures.
What are strings that hold together the centrioles?
Centrioles are held together by protein filaments called microtubules. The microtubules are arranged in a specific pattern to form the cylindrical structure of centrioles. These structures play a key role in organizing the microtubule network in the cell and are involved in cell division.
What does centrioles consist of?
Centrioles consist of microtubules arranged in a specific pattern known as a 9+0 or 9+2 arrangement. They play a crucial role in organizing the microtubule network during cell division and are involved in the formation of cilia and flagella in eukaryotic cells.
What is a nine fused microtubule at the core of an animal centrosome?
A nine fused microtubule at the core of an animal centrosome refers to a structure called a centriole. Centrioles are cylindrical arrays of microtubules arranged in a 9+0 pattern, meaning there are nine triplets of microtubules in a circle with no central microtubules. Centrosomes play a vital role in organizing the microtubule cytoskeleton and are involved in processes such as cell division and cell motility.
What is the complex assembly of micro-tubules that occur in pairs?
The complex assembly of microtubules that occurs in pairs is known as a "doublet." These doublets are primarily found in structures like cilia and flagella, where they play a crucial role in cellular movement. In these structures, nine pairs of microtubules are arranged in a circular pattern, with two additional microtubules in the center, forming a characteristic "9+2" arrangement. This configuration is essential for the motility and functionality of these organelles.
What other structures of the cytoskeleton would show the same pattern of microtubules as a flagellum?
Cilia, which are similar to flagella in structure, would also show the same pattern of microtubules. Both flagella and cilia contain a 9+2 arrangement of microtubules, with nine outer doublet microtubules and a central pair of microtubules.
What makes up cilia flagella and centrioles?
Cilia and flagella are made up of microtubules arranged in a 9+2 pattern, which consists of a central pair of microtubules surrounded by nine doublets. Centrioles are also composed of microtubules arranged in a 9+0 pattern. These structures play essential roles in cell motility and division.
What is the Starburst pattern formed by microtubules around the centriole?
The starburst pattern formed by microtubules around the centriole is called the astral array. These microtubules radiate outwards from the centriole like the rays of a star, providing structural support and helping to position the centriole during cell division. Additionally, the astral microtubules are involved in organizing the mitotic spindle and ensuring accurate chromosome segregation.
What are cilia and flagella made up of?
Cilia and flagella are made up of microtubules, specifically arranged in a 9+2 pattern. They consist of nine doublets of microtubules surrounding a central pair of microtubules. The movement of cilia and flagella is generated by the sliding of these microtubules past each other.
What are centrioles composed of?
Centrioles are composed of microtubules arranged in a specific pattern, typically in a cylindrical shape. They play a key role in organizing the microtubules of the cytoskeleton and are essential for cell division.
What other structures of the cytoskeleton would show the same pattern of microtubules a flagellum?
Cilia and lamellipodia

Centriole is composed of microtubules and important for organizing the spindle fibers?
Yes, centrioles are composed of microtubules and are essential for organizing the spindle fibers during cell division. They play a crucial role in cell division by helping to separate chromosomes. Each centriole is made up of nine triplets of microtubules.
What long hairlike projection on cells is composed by pairs of microtubules?
Cilia are the long hairlike projections on cells that are composed of pairs of microtubules arranged in a 9+2 pattern. They are involved in cell motility and sensing the external environment.
