The portion of the DNA molecule that can vary is its:
A. sugar
B. base
C. deoxyribose
D. ribose
E. phosphate
Answer (2)
Its' base can vary. The sugar (deoxyribose) stays the same. And the phosphate also stays the same. There are four different bases. The arrangement of the bases in threes are called condons. These code for amino acids. These make proteins which make us what we are. The codes are also called genes.
The portion of the DNA molecule that can vary is the nitrogenous base, which includes adenine, thymine, cytosine, and guanine. These variations are essential for forming the genetic code required for protein synthesis. Thus, the correct answer is option B: base.
