how plasmids help in giving antibiotic resistance to bacteria ?

Dear student

Please refer the solution below for the said query

The plasmids present in bacteria contain antibiotic resistance genes which provide them resistance in several ways. These genes may neutralize antibiotics and make it harmless or they may change the structure of outer covering so that antibiotics cannot attach to it and kill them.

Hope this information clears your doubt about the topic.
