Question
Which of the following does not occur during RNA processing?View Available Hint(s)for Part ESegments of RNA that do code for the protein are reconnected.Segments of the RNA strand that do not actually code for the protein are removed.Adenine nucleotides are added to the end of the RNA strand, forming a tail.mRNA attaches to the small subunit of a ribosome.A modified guanine nucleotide is added to the beginning of the RNA strand as a cap.
Solution
The option that does not occur during RNA processing is "mRNA attaches to the small subunit of a ribosome." This step is part of the translation process, not the RNA processing. During RNA processing, introns (segments of the RNA strand that do not actually code for the protein) are removed and exons (segments of RNA that do code for the protein) are reconnected. A modified guanine nucleotide is added to the beginning of the RNA strand as a cap, and adenine nucleotides are added to the end of the RNA strand, forming a tail. These modifications help to protect the mRNA molecule from degradation and aid in its export from the nucleus.
