The division of a bacterial cell into two daughter cells is accomplished by a protein called ftsz. ftsz is very similar to the tubulin 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. plant and animal cells also require cytoskeletal proteins for cytokinesis, although the roles these proteins play differ among bacteria, plants, and animals. for each space in the table, drag the appropriate label to indicate if the statement is true or false for each group of organisms. statement bacteria animals plantstrue cells divide by constriction of a ring of proteinthe presence of a cell wall prevents the cell fromby constrictiontubulin subunits or tubulin-like moleculesthe division of the cell

In a relatively small iguana population the allelic frequency is tracked for three generations. webbing is a recessive allele; no webbing is the dominant allele. during one very rainy spring and summer, a flood washes all the iguana without webbed feet out to sea. by the fall, and three generations later, you have the gene pool seen here.
