Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which part of a DNA molecule represents encoded information?
A
phosphate
B
sugar
C
guanine
D
hydrogen bond
Explanation: 

Detailed explanation-1: -DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base-A, C, T, or G-can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.

Detailed explanation-2: -The sequence of bases pairs encodes hereditary information concerning an organisms trait.

Detailed explanation-3: -Genetic Code Each gene’s code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T)-in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.

Detailed explanation-4: -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 .
