Question

the removal of sections of rna, called introns, occur at which regulation step in eukaryotic cells? (1 point)
mrna life span
post - translation
rna processing
chromatin remodeling

Explanation:

• mRNA life span: Refers to how long mRNA exists in the cell, not related to intron removal.
• Post - translation: Involves modifications to proteins after they are synthesized, not RNA processing.
• RNA processing: In eukaryotes, during RNA processing (specifically pre - mRNA processing), introns (non - coding regions of RNA) are removed and exons (coding regions) are joined together.
• Chromatin remodeling: Deals with changes in chromatin structure (DNA + proteins) to regulate gene expression at the DNA level, not at the RNA level for intron removal.

Answer:

RNA processing
