Which of the following are involved in post-transcriptional control?
control of rna splicing
control of rna shuttling
control of rna stability
all of the above

All of the above

Explanation:

Post-transcriptional control is that which is carried out after the transcription process, i.e. on the RNAm.

Among them you can find them:

control of RNA splicing: process by which the introns of the RNA sequence are eliminated.

control of RNA shuttling: maintenance process and transport of RNA to the cytoplasm

control of RNA stability: modifications on the extremes 5´ (Capping) and 3´ (poli A Tail)
