Which of the following statements about eukaryotic RNA is true?

Question

Quizplus · Accepted Answer

In eukaryotes, primary RNA transcripts contain both introns and exons. The introns are removed and exons are spliced together to form the final mRNA molecule, which is then transported out of the nucleus for translation. While some modifications occur to the RNA molecule, such as the addition of a 5' cap and a 3' poly-A tail, introns are not added to the RNA. Additionally, RNA molecules are not transported into the nucleus; rather, they are transcribed from DNA within the nucleus and then transported out of the nucleus.
