RNA splicing is the process of

• A. synthesizing RNA from DNA
• B. removing introns and connecting the exons
• C. adding a 5' cap
• D. polyadenylating the transcript

Answer: (B)

RNA splicing is the step in mRNA maturation where introns are removed and exons are joined to form a continuous coding sequence. This editing occurs after transcription in the nucleus and is carried out by the spliceosome, a complex of proteins and small nuclear RNAs. It does not involve synthesizing RNA from DNA (that’s transcription), nor does it describe adding a 5′ cap or polyadenylating the transcript (those are separate processing steps that stabilize and prepare the mRNA for export). Splicing enables the mature mRNA to be translated and, in some cases, allows alternative splicing to produce different protein variants from the same gene.
