Which of the following is not involved in post- transcriptional control. DNA transcription occurs in a cells nucleus. Shortens target mRNA half-lives and thus the abundance of functional proteins 14151718.

Which of the following are involved in post-transcriptional control. LRF has been shown to be a specific transcriptional repressor of p19ARF The transient over-expression of miR-20a shows that 48 hours post transfection the level of LRF mRNA was almost unchanged while it was reduced following a si-RNA specific for LRF si-LRF Figure 2a. The period between transcription and translation is called post transcription level.

All of the above. MiR-20a over-expression induces p19ARF. This processing results in an RNA sequence that is different from that encoded by.
