Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What makes up the genetic code in DNA?
A
the phosphate group
B
the nitrogen bases
C
the deoxyribose sugar
D
the ribose sugar
Explanation: 

Detailed explanation-1: -Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, the thymine is replaced by uracil (U).

Detailed explanation-2: -The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.

Detailed explanation-3: -DNA base pair. 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-4: -The order of nitrogenous bases in DNA is arranged in such a way that they code for the protein molecule (that is Amino acids).
