Cell Wall Growth Patterns of a Variety of Bacteria Have

question 16

Multiple Choice

Cell wall growth patterns of a variety of bacteria have been studied using fluorescently labeled D-amino acids. This approach has worked because

• A) fluorescent amino acids block further cell wall synthesis and thus provide a snapshot of the cell wall at a particular time.
• B) ribosomes cannot incorporate any fluorescence and thus cannot use fluorescent amino acids; it all goes to cell wall.
• C) vancomycin can block the incorporation of D-alanine into protein and thus force it into the cell wall.
• D) the labeled amino acids are D-amino acids, not L-amino acids.; thus, they only were incorporated into cell wall.
• E) This approach has not worked.
