Which of the following would be selective against the tubercle bacillus? Group of answer choices streptogramin – inhibits protein synthesis vancomycin – inhibits peptidoglycan synthesis ethambutol – inhibits mycolic acid synthesis streptomycin – inhibits protein synthesis bacitracin – inhibits peptidoglycan synthesis

C) ethambutol inhibits mycolic acid synthesis

Explanation:

Ethambutol is an antimycobacterial agent which is used in the treatment of tuberculosis. However, Ethambutol is to be given in combination with some other drug.  

It inhibits the tubercle bacillus and synthesis of spermidine in mycobacteria  by inhibiting the transfer of mycolic acids into the cell wall which further stimulates the synthesis of trehalose dimycolates  This is bactericidal and may produce lethal effect if it penetrates into the human cell.  

Option C is the right choice of answer

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
