- Q8Why are bacteria becoming resistant to penicillins?They cannot synthesize folateThey have no ribosomesThey lack cell wallsThey produce enzymes that destroy beta-lactam rings30s
- Q9What is the role of ribosomes in bacterial cells?To synthesize proteinsTo form cell wallsTo replicate DNATo produce folate30s
