Animal Cells Microtubules at viijiannablog Blog


Animal Cells Microtubules. They are found throughout the cytoplasm in eukaryotic plant and animal cells. A single microtubule contains 10 to 15 protofilaments (13 in mammalian cells) that wind together to form a 24 nm wide hollow cylinder.

A single microtubule contains 10 to 15 protofilaments (13 in mammalian cells) that wind together to form a 24 nm wide hollow cylinder. Microtubule, tubular structure of indefinite length, constructed from globular proteins called tubulins, which are found only in eukaryotic cells. Microtubules extend throughout the cell providing it with proper shape and keeping the organelles in place.

Like the other two cytoskeletal elements, microtubules play a crucial role in cell division, movement, and maintaining cell shape. Like the other two cytoskeletal elements, microtubules play a crucial role in cell division, movement, and maintaining cell shape. They are the largest structures in the cytoskeleton. Microtubules, the third principal component of the cytoskeleton, are rigid hollow rods approximately 25 nm in.
