What are cilia and flagella made up of?
They are composed of microtubules in a "9 + 2" array, similar to centrioles but with two additional microtubules in the center.
In animal cells microtubules grow from which structure?
centrosomes
If an individual has abnormal microtubules due to a hereditary condition in which organs or tissues would you expect dysfunction?
all ducts, such as those from salivary or sebaceous glands
Why is colchisine used in karyotypic determination?
Colchicine causes microtubules to depolymerise. During cell division at the metaphase stage condensed chromosomes line up and are then pulled apart to either pole by microtubules. Hence adding colchicine to a cell culture stops cells completing mitosis. This is useful as a means of accumulating metaphases in the culture before harvesting. Typically colchicine (or the less toxic colcemid) is added about 30mins to 1 hour before harvesting, varying depending on cell type, species etc.
What is Sliding microtubule hypothesis?
The sliding microtubule hypothesis explains how cargo (such as amino acids and other small molecules) travel down the minus end of the microtubules (towards the nucleus) by a pair of dynein arms. These dynein arms periodically project out from the peripheral microtubule doublet.
What makes up cilia flagella and centrioles?
microtubules
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.
Which cytoskeletal element radiates from the cell center?
Microtubules radiate from the cell center.
What produces microtubules during cell division in animals?
kinetochore microtubules are located in the centrosomes and produce the microtubules
What is the stystem of microtubules?
The Cytoskeleton is a system of microtubules, in a cell.
Organelles used to move chromosomes are the?
microtubules
The hollow tubes of protein that help maintain the shape of the cell is what?
microtubules.... might be right
Spindle fibres are composed of?
They are made up of clusters of microtubules. Microtubules are made of the protein tubuliln and are responsible for cell movement and shape. The microtubules are like "conveyor belts" inside the cell.
Spindle fibers are present in what stage of mitosis?
Prophase its actually in an indistinct phase called prometaphase and they are formed by the kinetochores putting together microtubules, which makes up the microtubules
What microtubules are necessary for sorting the chromosomes in cell division?
The kinetochore microtubules
What are spindle fibers composed of?
spindle fibers are composed of what? Answer: Microtubules
Which cytoskeleton fibers are found in cilia and flagella?
microtubules
