Question

How ar RNA AND DNA similar? How are they different?

Answer 1

"In DNA thymine pairs with adenine, but in RNA uracil pairs with adenine. Similarities: - DNA and RNA are made up of monomers called nucleotides. - DNA and RNA both have 3 nitrogenous bases: Adenine, Cytosine and Guanine."

Answer 2

Both DNA and RNA are polymeric molecules, meaning they are formed from many repeating units, formed from a sugar-phosphate backbone and genetic bases. However the sugar in the DNA backbone is deoxyribose, while in RNA it is ribose, and while DNA and RNA both use Adenine (A), Cytosine (C) and Guanine (G) bases, DNA uses Thymine (T) which is replaced by Uracil (U) in RNA. Additionally, DNA is almost always double stranded, while RNA can be double or single stranded, depending on the organism the RNA is from.
Hope this helps!
