Which process involves the removal of non-coding sections from a pre-mRNA molecule during RNA modification and processing?
A
Polyadenylation
B
Transcription
C
Splicing
D
Capping
Verified step by step guidance1
Understand that the question is asking about a process that modifies pre-mRNA by removing certain sections before it becomes mature mRNA.
Recall that pre-mRNA contains both coding regions called exons and non-coding regions called introns.
Identify that the process which removes the non-coding introns from pre-mRNA is called splicing.
Recognize that other options like polyadenylation add a poly-A tail, capping adds a 5' cap, and transcription is the synthesis of RNA from DNA, so they do not involve removal of non-coding sections.
Conclude that splicing is the correct process responsible for removing non-coding sections (introns) from pre-mRNA during RNA processing.
