Answer:

RNA is mostly single-stranded; DNA is always double-stranded.

Step-by-step explanation:

DNA stores the genetic information that codes for the way protein should be developed by the cell. Protein determines the trait (phenotype) of the cell/organism. RNA is used as an intermediary between DNA and proteins. RNA is made of ribonucleic acids while DNA is made of deoxyribonucleic acids.
