Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The bases of DNA include which of the following?
A
Adenine
B
Guanine
C
Uracil
D
Thymine
E
Cytosine
Explanation: 

Detailed explanation-1: -There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).

Detailed explanation-2: -A chemical compound that is used to make one of the building blocks of DNA and RNA. It is a type of pyrimidine.

Detailed explanation-3: -A segment of DNA has 120 adenine and 120 cytosine bases.

Detailed explanation-4: -c) Cytosine: It is present in both DNA and RNA. It is a pyrimidine and pairs with guanine (purine) by a triple hydrogen bond.

Detailed explanation-5: -The bases can be categorized into two different groups. The single-ring nitrogenous bases, thymine and cytosine, are called pyrimidines, and the double-ring bases, adenine and guanine, are called purines.
