Bacteria are single-celled organisms usually found all over the inside and outside of our bodies
Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic
Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections,the bacteria survive and continue to multiply causing more harm
There are two main ways that bacterial cells can acquire antibiotic resistance,one is through mutations that occur in the DNA of the cell during replication and the other way that bacteria acquire resistance is through horizontal gene transfer
Through the process of replication bacteria develop mutations that make them resistant to antibiotics
Bacteria with the resistant mutation have a better chance of survival against antibiotics
Resistant bacteria continue to multiply even when exposed to antibiotics
In horizontal gene transfer,antibiotic resistant genetic material is transferred between different bacterial cells which can happen in three different ways: transformation,transduction or conjugation
