The three components of RNA are a phosphate group, ribose sugar, and a nitrogenous base How are the base pairs different?

The nitrogenous bases Adenine (A), pairs with uracil (U), while guanine (G) and cytosine (C) pair up.

Explanation:

Nucleotides are monomers that make up DNA and RNA- these are nucleic acids that function as storage, transport and messenger molecules for encoding proteins. Nucleotides contain a 5-carbon deoxyribose (with hydroxyl modifications) or ribose sugar (RNA), phosphate and one of four nitrogenous bases:

Adenine (A)

Guanine (G)

Cytosine (C)

Thymine (T).- DNA only

Uracil (U) found in RNA

Nucleotide monomers derive their names from their bases. Nucleic acid polymers form on a single strand through covalent bonding. This occurs between two nucleotides in an esterification reaction where a phosphodiester bond is formed.

Nitrogenous bases encourage hydrogen bonding, and resulting base pair formation.  Adenine (A), pairs with uracil (U), while guanine (G) and cytosine (C) pair up.
