Question

Metabolic reactions leads to transformation of biomolecules. Removal of an amino group in a nucleotide base (AMP) leads to formation of

• A. Nucleoside
• B. Nucleotide with purine
  
• C. Pentose sugar and Phosphate
  
• D. None of these

Answer 1

Answer: (C)

Pentose sugar and Phosphate

Nucleotides are the building blocks of nucleic acids. They are composed of three subunit molecules: a nitrogenous base, a five-carbon sugar ( ribose or deoxyribose ), and at least one phosphate group. Hence, removal of the amino group ( nitrogenous base ) from nucleotide leaves behind a pentose sugar and phosphate groups.

So, the correct option is 'Pentose sugar and Phosphate'.
