Verified step by step guidance1
Understand that the problem is asking about a process that occurs after transcription in eukaryotic cells.
Recall that pre-mRNA is the initial transcript that is synthesized from the DNA template during transcription.
Identify that pre-mRNA contains both exons (coding regions) and introns (non-coding regions).
Recognize that the process of removing introns from pre-mRNA is called splicing.
Note that splicing is carried out by a complex called the spliceosome, which ensures that only exons are joined together to form mature mRNA.
