Final answer:
Transcription-splicing coupling refers to the coordination between the processes of transcription and splicing in eukaryotic cells. It ensures that only the correct RNA sequences are synthesized and minimizes potential errors.
Step-by-step explanation:
Transcription-splicing coupling refers to the coordination between the processes of transcription and splicing in eukaryotic cells. Transcription is the process of synthesizing an RNA molecule from a DNA template, while splicing involves the removal of introns and joining together of exons in the nascent RNA transcript. The coupling of these two processes allows for efficient and accurate removal of introns and production of mature mRNA. It ensures that only the correct RNA sequences are synthesized and minimizes the potential for errors.
