Answer
Without additional context or a specific gene reference, this statement cannot be confirmed as true. Generally, genes may have varying numbers of introns.

Answer
This statement lacks clarity as RNA polymerase is generally involved in transcription (commonly referred to as Step 1) rather than a hypothetical Step 3.
