An otherwise healthy student in your class is infected with EBV, the virus that causes infectious mononucleosis. The same student had already been infected when she was a child, and she had merely experienced a mild sore throat and swollen lymph nodes in her neck. This time, though infected, she does not get sick. 

Her immune systemʹs recognition of this infection will involve which of the following?

Arrange the steps of stages in PCR in correct order.

1. The region to be specifically amplified is made accessible within the complex DNA.

2. The double stranded DNA is denatured by heating the reaction mixture to above 90 degree Celsius.

3. A thermal cycler is used to incrementally decrease the annealing temperature.

4. Reaction mixture is then cooled to a temperature between 40 and 60 degree celsius.
