Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which has 4 nitrogen bases?
A
DNA
B
RNA
C
Both
D
None of the above
Explanation: 

Detailed explanation-1: -Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).

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. The binding of these base pairs forms the structure of DNA .

Detailed explanation-3: -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-4: -Hence, Adenine, Guanine, and Cytosine are common to both DNA and RNA.

Detailed explanation-5: -The nitrogen bases are held together by hydrogen bonds: adenine and thymine form two hydrogen bonds; cytosine and guanine form three hydrogen bonds.
