$RNA$ polymerases used for the transcription of genes require a template.

Identify $X$ in the given figure.

If the template strand of $DNA$ is $3'-CTGATAGC-5'$,what will be the sequence of the transcribed $RNA$?

The process of synthesis of $m-RNA$ from $DNA$ is called ......

Given below are the two statements.
Statement $I$: Only one strand in the transcription unit functions as a template and is called the antisense strand.
Statement $II$: The non-template strand of the transcription unit is called the sense strand.
In the light of the above statements,choose the correct answer from the options given below.

In eukaryotes,the entire base sequence of a gene does not appear in mature $RNA$ because
