Question

Which is not a nucleotide component?
A. Thymine
B. Guanine
C. Lysine
D. Adenine

Answer 1

In DNA, guanine, adenine, cytosine and thymine are the four Nitrogen Bases. In RNA, uracil is used rather than thymine.

Complete answer:
Nucleotides consist of a nucleoside and a Phosphate in organic molecules. The monomeric units of the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) nucleic acid polymers are important biomolecules of any life form on Earth. At the basic, cellular level, nucleotides play a key role in metabolism. The energy they generate in cells for the many cell functions that need energy including: amino acid, cell protein and membrane synthesis and moving the cell and cell parts, cell and cell functions, such as nucleoside triphosphates, adenosine triphosphates (ATP), guanosine triphosphatases, cell cytidine triphosphate, uridine triphosphate. Furthermore, nucleotides are involved in cell signals, which is integrated into essential enzyme cofactors.

Nucleotides contain three molecules of subunits: the nitrogen base (also referred to as nucleobase), the five-carbon sugar (ribose or deoxyribose), and the one to three phosphates containing a phosphate group. In DNA, guanine, adenine, cytosine and thymine are the four Nitrogen Bases; in RNA, uracil is used rather than thymine.

Lysine is an amino acid (protein construction block). People make medicine with it. Lysine seems to assist the body in processing calcium, which plays an important role in producing collagen, an important material for bones and connective tissue, including tendons, skin, and cartilage.

Thus, the correct answer is option C. i.e., Lysine.
