How to protect RNA from degradation?

To protect RNA from degradation, you can:  RNA is prone to enzymatic degradation and hydrolysis. Even at low temperatures, RNA can still be reactive, and some ribozymes can be enhanced by […]

What is the main reason for RNA being unstable?

Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation. RNA is generally stable at –80° […]
