उत्तर
This statement is true.
Explanation:
The primary transcript (or pre-mRNA) contains both exons, which code for proteins, and introns, which are non-coding sequences. During the process of RNA splicing, the introns are removed, and the exons are joined together to create the mature mRNA. Because introns often make up a large portion of the gene's length, their removal significantly shortens the molecule before it leaves the nucleus for translation.
