Notochord Definition An elastic rod, found in all chordate organisms, is known as the notochord. It provides rigid support to the organism. The notochord is replaced by the vertebral column in chordates, called the vertebrates. It is formed by a cartilaginous substance between vertebrae. Lancelets are one of the simplest
Table of Contents Microtubule Definition Microtubules are a part of a cell’s cytoskeleton. They are hollow tubes made of the proteins alpha and beta tubulins. Microtubulin form a network of protein filaments extended throughout the cell that gives the cell shape. Microtubules are thicket among all the structures in the

What are Cytoskeleton? The presence of cytoskeleton in the design of the cellular material was proposed by Koltzoff in 1928. They are intertwining organization of protein fibers stretched out all through the cytoplasm and lattice of various proteins in cells. As its name infers it assists with keeping up with
