Answer:
The nitrogenous bases Adenine (A), pairs with uracil (U), while guanine (G) and cytosine (C) pair up.
Step-by-step 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.
