Question

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

Explanation:

Introns are non-coding segments of RNA that are removed from pre-mRNA to form mature mRNA. This modification of RNA molecules is the defining feature of RNA processing in eukaryotic gene expression regulation. The other options do not involve intron removal: chromatin remodeling affects DNA accessibility, mRNA life span relates to mRNA stability, and post-translation involves modifications to proteins.

Answer:

RNA processing
