Why does RNA degradation take place? ~~> Damaged mRNA Incorrectly transcribed/processed mRNA Control gene expression What 2 things control mRNA levels? ~~> Transcription and turnover Why is turnover important? ~~> If mRNA has a ridiculously long half life and doesn't go away, then if you stop transcription you don't stop protein expression because the mRNA is still there Describe what casein mRNA is and explain the importance of turnover ~~> Expressed in mammar...
