What else can I help you with?
Organelles used to move chromosomes are the?
microtubules
What structures carry out cell movement?
a. cytoplasm and ribosomes b. nucleolus and nucleus c. microtubules and microfilaments d. chromosomes answer is c. microtubules and microfilaments
Which structure carry out cell movement?
Microtubules and Microfilaments.
Structural features that spatially organize the interior of the cell are?
microtubules
How do you explain the differences in the apparent shapes and positions if the nuclei in different cells?
Nuclear size and shape are determined by a number of factors. Size: Amount of genetic material, fluid, proteins and byproducts of the transcription process. Shape: Most nuclei are "anchored" in the cell by microtubules that are coordinated by the centrosomes. This internal structure works a lot like steel beams when constructing home or other buildings. Position: Is also determined by the relationship between motor proteins that are attached to the nuclear envelope and the microtubules.
Is the mitotic spindle primarily composed of microtubules?
Yes, the mitotic spindle is primarily composed of microtubules.
What are spindle fibers composed of?
Spindle fibers are composed of microtubules, which are polymers of the protein tubulin. These microtubules play a crucial role in cell division by helping to separate the chromosomes during mitosis and meiosis.
The cilia and flagella of eukaryotic cells are composed of?
Virtually all eukaryotic cilia and flagella are composed of a central bundle of microtubules. This bundled arrangement is called an anoxeme. In the anoxeme, nine outer doubled microtubules surround an inner pair of single microtubules.
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.
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.
Which cytoskeletal element is NOT correctly associated with its characteristics?
C. Centrioles are found in the microtubule organizing centers of plants.
What is The internal skeleton of a cell is composed of?
Microtubules, Intermediate Filaments, and M icrofilaments
What is a short hair like projection on a cell's surface that are composed of microtubules?
flagella
What are short hairlike projections on cell surface that are composed of microtubules?
eukaryotic cells
What is the internal skeleton of the cell composed of?
Microtubules, Intermediate Filaments, and M icrofilaments
Spindle fibers are made of hollow tubes of protein called what?
Spindle fibers are made of microtubules, which are composed of the protein tubulin. These microtubules play a critical role in the segregation of chromosomes during cell division.
What material makes up flagellum?
Flagella possess a central bundle of microtubules in which nine outer double microtubules surround a central pair of single microtubules. This characteristic "9 + 2" arrangement of microtubules is also seen in cilia.
