Solution Summary

The solution answers with small explanation multiple molecular biology questions.

Solution Preview

1. mRNA turnover in eukaryotic cells looks to distinguish between transcripts that are actively translated and those that are not. In bacteria, sRNA can stimulate mRNA degradation via nucleases whereas in eurkaryotic cells mRNA degradation complexes.

2. snoRNAs serve to guide modifications on RNAs. These modifications could by ...
