The division of a bacterial cell into two daughter cells is accomplished by a protein called FtsZ. FtsZ is very similar to the t
ubulin subunits that form microtubules in eukaryotes. After the replicated bacterial chromosomes have moved to opposite ends of the cell, a ring of FtsZ proteins forms inside the plasma membrane in the region where the cell will divide. As the FtsZ ring constricts, the plasma membrane and bacterial cell wall fold in and eventually separate into two cells.
The correct answer is FtsZ is very similar to the tubulin subunit that form microtubules in eukaryotes.
Explanation:
FtsZ protein plays a significant role during bacterial cell division.FtsZ is a GTP binding protein and also contain GTPase enzyme that helps in the hydrolysis of ATP .
The principle function of FtsZ protein is to form filament in which the subunits are arranged in a specific manner.The filament then form a ring like structure which is called Z ring.
The movement of subunits of FtsZ generate force that helps the cell to divide.
The bald eagle and the black bear are tetrapods, which means that they both have four limbs along with the digits. This shows that they both are the descendants of the four-limbed ancestors. However, the limbs of the bear and the bald eagle have different functions. The forelimbs of both these organisms serves different purpose. Hence, their limbs are homologous organs. The homologous organs are those which have the same ancestry but the functions are different.
