A simple diagram of a DNA molecule is shown below. Which of the following is represented by X?
Reil [10]

Answer:

From the diagram X = <u>base pairs</u>

Explanation:

Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.

Nucleotides comprise:

  • a 5-Carbon deoxyribose sugar,
  • one nitrogenous base (adenine, guanine thymine, and cytosine)
  • and a phosphate group.

Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides  Thymine and Cytosine (pyrimidine bases) along with Guanine,  and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.
