Question

The removal of sections of RNA, called introns, occur at which regulation step in eukaryotic cells

Answer 1

The removal of introns occurs during post-transcriptional regulation in eukaryotic cells. This process, called splicing, involves the removal of introns from pre-mRNA and the joining of exons to form mature mRNA. Splicing is carried out by the spliceosome complex.

Answer 2

The removal of introns from RNA molecules occurs during the post-transcriptional regulation step in eukaryotic cells.

Step-by-step explanation:

During transcription, RNA molecules are synthesized from DNA templates. In eukaryotic cells, the RNA molecules produced during transcription are called pre-mRNA, which contain both exons (coding regions) and introns (non-coding regions). The introns are removed from the pre-mRNA molecule in a process called splicing, which occurs during post-transcriptional processing.
