one nitrogenous base (adenine, guanine thymine, and cytosine)
and a phosphate group.
Explanation:
Nucleotides are monomers that makeup DNA- a nucleic acid that functions as a storage molecule for encoding proteins, along with RNA a ribose sugar-containing nucleotide. Nucleotides contain a 5-carbon deoxyribose or ribose sugar, phosphate and one of four nitrogenous bases:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T).
Uracil (U) found in RNA
Each nucleotide derives its name from its nitrogenous base. The nucleotides on a single strand polymerize via covalent bonding. This occurs between two nucleotides in an esterification reaction where a phosphodiester bond is formed. In double helix formation, base pairs form hydrogen bonds with each other.
Answer: Roles of DNA polymerases and other replication enzymes. ... which require a template and a primer (starter) and synthesize DNA in the 5' to 3' direction. ... Topoisomerase also plays an important maintenance role during DNA replication.
