From Molecular Biology: How Bacterial Immunity Became Gene Editing
Why is DNA better suited than RNA for storing genetic information long term?
- Its sugar lacks a reactive oxygen group
- It uses four bases rather than three
- It is always wrapped inside proteins
Show the answer
Answer: Its sugar lacks a reactive oxygen group
RNA's extra hydroxyl group on the sugar makes its backbone prone to breaking; DNA's 'deoxy' sugar is far more stable.
