what bonds nitrogenous bases together to form base pairs?
The bonds that connect nitrogenous bases to form base pairs in nucleic acids, such as DNA and RNA, are called hydrogen bonds
The bonds that connect nitrogenous bases to form base pairs in nucleic acids, such as DNA and RNA, are called hydrogen bonds.
A nitrogenous base is a molecule that contains nitrogen and is a crucial building block of nucleotides, the monomeric units of nucleic acids. There are four nitrogenous bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, uracil (U) replaces thymine.
The base pairs in DNA are formed by complementary binding of the bases. Adenine forms two hydrogen bonds with thymine, while cytosine forms three hydrogen bonds with guanine. This is called complementary base pairing. The hydrogen bonds involve the hydrogen atom(s) from one base forming a weak electrostatic interaction with the nitrogen or oxygen atom(s) of the complementary base.
These hydrogen bonds in base pairs are relatively weak individually, but when multiple base pairs are present in a DNA or RNA strand, they collectively provide significant stability to the double-stranded structure. The specific hydrogen bonding pattern between the base pairs plays a crucial role in maintaining the structure and function of nucleic acids, such as DNA replication and protein synthesis.
