Given : $Cr _2 O _7^{2-} \rightarrow Cr ^{3+} ; E ^0=1.330\,V$ and

$\frac{2.303 RT }{ F }=0.059\,V$

The potential for the half cell reaction is $x \times 10^{-3}\,V$. The value of $x$ is $........$

$(1)$ Denaturation of proteins causes loss of secondary and tertiary structures of the protein.

$(2)$ Denaturation leads to the conversion of double strand of $DNA$ into single strand.

$(3)$ Denaturation affects primary structure which gets distorted.
