Detailed explanation-1: -Two nitrogen-containing bases (or nucleotides) that pair together to form the structure of DNA. The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).
Detailed explanation-2: -Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together.
Detailed explanation-3: -Nitrogenous bases, also called nucleobases, are nitrogenous compounds that form an important part of the nucleotides. Nucleotides are building blocks of DNA and RNA that are composed of a sugar, nitrogenous base and a phosphate group.
Detailed explanation-4: -Last time we saw that each nucleotide contains a nitrogenous base: adenine, cytosine, guanine or thymine. All of these molecules are called nitrogenous bases because they contain nitrogen atoms. The lone pairs of electrons on these nitrogen atoms are critical for binding DNA together [1].
Detailed explanation-5: -The nitrogenous bases in DNA are adenine, guanine, cytosine, and thymine. Adenine pairs with thymine and cytosine pairs with guanine. The ‘pairing’ occurs because the complementary bases form hydrogen bonds with each other.
