RNA splicing in eukaryotic cell protein synthesis means
A)that the product of translation,called the primary transcript is cut and put back together to produce the mature mRNA transcript.
B)that the product of transcription,called the secondary transcript is cut and put back together to produce the mature tRNA transcript.
C)that the product of translation,called the primary transcript is cut and put back together to produce the mature tRNA transcript.
D)that the product of transcription,called the primary transcript is cut and put back together to produce the mature mRNA transcript.

Question

Quizplus · Accepted Answer

RNA splicing refers to the process of removing introns (non-coding regions) from the primary transcript (also known as pre-mRNA) and joining together the exons (coding regions) to form the mature mRNA transcript. Therefore, option D is the correct answer as it describes the correct product of transcription (primary transcript) and the correct final product of RNA splicing (mature mRNA transcript). Option A is incorrect because it refers to the product of translation (rather than transcription) and also because splicing occurs before translation. Option B is incorrect because it refers to tRNA (transfer RNA) rather than mRNA. Option C is incorrect for the same reason as option A.
