WebQuestion: Antibiotics are molecules that bind to important structures in bacteria, but not in human cells, and so can be used to suppress the growth of bacteria in the human body, but have no effect on the human cells. (i) There is a class of antibiotics that act by binding in the P site of the large subunit of the bacterial ribosome, thereby blocking tRNA binding. class cdl california tests WebMade up of cell or parts cell cell nucleic acid ( part of cell) Has a nucleus yes lack true nucleus ( nucleoid) no.
