Read the following statements and select the correct statements:
$(A)$ Essential life processes such as metabolism,translation and splicing are evolved around $\text{RNA.}$
$(B)$ Heavy isotope of nitrogen $(^{15}N)$ is a radioactive isotope,while light isotope of nitrogen $(^{14}N)$ is not a radioactive isotope.
$(C)$ The codon in $\text{rRNA}$ is read in a contiguous fashion.

Choose the correct answer from the options given below:

Statement-$I$: The split gene arrangements represent probably an ancient feature of the genome.
