The Fragile Messenger: RNA Stability Explained

RNA is chemically reactive by design, and that reactivity has real consequences for how long any given RNA molecule survives inside the cell. Rna stability explained explores how the 2' hydroxyl group on ribose makes RNA...

Questions: 20 | Attempts: 12 | Last updated: Mar 2, 2026

Sample Question 1
What chemical group on the ribose sugar makes RNA significantly less stable than DNA?

2' hydroxyl group (-OH)

3' phosphate group

5' carbon

Nitrogenous base

Hydrogen bond

Sample Question 2
The term RNA Stability refers to how long an RNA molecule remains intact before it is broken down by chemical or enzymatic processes.

True

False

Sample Question 3
Why does RNA undergo rapid hydrolysis in alkaline (high pH) conditions?

Hydroxyl ions deprotonate the 2'-OH group

The bases turn into sugar

The phosphate group disappears

The RNA turns into DNA

The water freezes
