Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which component of DNA determines the traits of an organism?
A
Nitrogen Bases
B
Sugar-Phosphate Backbone
C
Hydrogen bonds
Explanation: 

Detailed explanation-1: -The order of the Nitrogen Bases determines the traits that an organism will possess (have).

Detailed explanation-2: -Gene. A segment of a DNA molecule (a sequence of bases) that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism.

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: -Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine).
