What are the 3 difference between DNA and RNA

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans.

DNA:

A pairs with T, Its a double helix, and it has sugar deoxyribose

RNA: U pairs with T, single stranded, and is has sugar ribose

Hope this helps :)

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
