Question

What products would be formed when a nucleotide from DNA containing thymine is hydrolyzed ?

Hint:

Hydrolysis of any nucleotide gives three components: a nitrogenous base, a pentose sugar and phosphoric acid.

Answer 1

Concept: A nucleotide is the fundamental structural unit of nucleic acids. Each nucleotide consists of three components:

• A nitrogenous base

• A pentose sugar

• A phosphate group
In DNA, the nitrogenous bases are adenine, guanine, cytosine and thymine. When a nucleotide undergoes hydrolysis, these components separate from one another.

Step 1: Identify the nucleotide The question specifies a DNA nucleotide containing thymine. Therefore the nucleotide contains:

• Thymine (nitrogenous base)

• Deoxyribose sugar

• Phosphate group

Step 2: Hydrolysis of the nucleotide Upon hydrolysis, the glycosidic bond and phosphate ester bond are broken. As a result, the nucleotide splits into its individual components.

Products formed \[ \boxed{\text{Thymine}} \] \[ \boxed{\text{2-Deoxyribose sugar}} \] \[ \boxed{\text{Phosphoric acid (phosphate group)}} \]

Final Answer: \[ \boxed{ \text{Thymine + 2-Deoxyribose Sugar + Phosphoric Acid} } \]
