In the case of polymerase chain reaction $(PCR)$,what are the temperatures required for the following steps?
$A.$ Denaturation
$B.$ Annealing
$C.$ Extension

An artificial process of infecting cells with naked viral $DNA$ is:

In which step of $PCR$ do the primers anneal to the $DNA$ template?

Arrange the steps of $\text{rDNA}$ technology in the correct order$:-$
$(I.)$ Extraction of the desired gene product.
$(II.)$ Amplification of the gene of interest.
$(III.)$ Isolation of the desired $\text{DNA}$ fragment.
$(IV.)$ Ligation of the $\text{DNA}$ fragment into a vector.
$(V.)$ Insertion of $\text{rDNA}$ into the host.
The correct order is$:-$

Identify the given figure.

Which of the following range of temperature is required for denaturation,annealing of primer,and primer extension of $PCR$ respectively?
