Verified step by step guidance

Understand the context: In eukaryotic cells, the initial RNA transcript produced during transcription is called pre-mRNA. This pre-mRNA contains both exons (coding regions) and introns (non-coding regions).
Identify the process: The removal of introns from pre-mRNA is known as splicing. This process is essential for converting pre-mRNA into mature mRNA, which can then be translated into proteins.
Explore the mechanism: Splicing is carried out by a complex called the spliceosome, which recognizes specific sequences at the intron-exon boundaries and catalyzes the removal of introns.
Differentiate from other processes: Translation is the process of synthesizing proteins from mRNA, replication is the duplication of DNA, and transcription is the synthesis of RNA from a DNA template. None of these processes involve the removal of introns.
Conclude with the correct answer: The process that removes introns from pre-mRNA is splicing, which is distinct from translation, replication, and transcription.
