Question

This structure’s flexibility and protein binding ability is mediated by zwitterionic molecules that are synthesized and deposited by “Tar” enzymes like TarO and TarA. The shape of this structure can be regulated by the ping-ponging mechanism of MinC, MinD, and MinE. The divisome regulates the division of this structure by recruiting FtsZ (“F-T-S-Z”) into a contractile ring. These structures often incorporate teichoic acids in between units of a macromolecule (10[1])whose D-ala-D-ala motifs allow for the crosslinking of NAG and NAM (10[1])residues. (10[1])The organisms which contain these structures can be characterized by whether or not these structures retain crystal violet following (10[1])a Gram (10[1])stain. For 10 points, name these structures composed primarily of peptidoglycan in bacteria. ■END■ (10[1])

ANSWER: bacterial cell wall [prompt on bacterial cell envelope; prompt on peptidoglycan or sacculus]
