The cytoskeleton of eukaryotic cells is made of filamentous proteins and provides mechanical support to the cell and its parts.
All cytoskeletons consist of three major classes of elements that differ in size and in protein composition. Microtubules are
the largest type of filament, with a diameter of about 25 nm and they are composed of a protein called tubulin while Actin
filaments are the smallest type with a diameter of about 6 nm and Intermediate filaments are mid-sized, with a diameter of
about 10 nm. Microtubules radiate out from the centrosome to provide the basic organization of the cytoplasm, including the
positioning of cellular organelles.
Microtubules have several other important functions. AL BUT ONE is a function of cellular microtubules.
Function in intracellular transport
Aid in cell division and chromosome movement
Aid in assembling amino acids during protein synthesis.
Function in movement as they compose the cilia and flagella of animal
cells.

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b
