What is 9 plus 0 structure of micro-tubules?

Answer 1

The "9 plus 0" structure of microtubules refers to the arrangement found in certain types of cilia and flagella, where there are nine outer doublet microtubules surrounding a central pair of microtubules. This configuration is characteristic of the axonemes of motile cilia and flagella, providing structural support and facilitating movement. In contrast, the "9 plus 2" arrangement, which includes two central microtubules, is typical of other cilia and flagella. The "9 plus 0" structure is often associated with non-motile cilia, which play roles in sensory functions rather than movement.

Answer 2

The "9 plus 0" structure of microtubules refers to a specific arrangement found in certain types of cilia and flagella. In this configuration, there are nine doublet microtubules arranged in a ring surrounding a central pair of microtubules, making it a total of 9 outer doublets and 0 central microtubules. This structure is characteristic of non-motile cilia and some sensory organelles, as opposed to the "9 plus 2" arrangement found in motile cilia and flagella, which includes two central microtubules. The "9 plus 0" configuration plays a crucial role in cellular signaling and sensory functions.
