what products would be formed when a nucleotide from dna containing thymine is hydrolysed
When a nucleotide from DNA containing thymine is completely hydrolysed, it breaks down into three separate components: thymine, 2-deoxyribose sugar, and phosphoric acid.
Direct answer
The products formed are:
- Thymine (nitrogenous base)
- β-D-2-deoxyribose (the deoxyribose sugar)
- Phosphoric acid (H₃PO₄) (the phosphate group)
Quick Scoop: what’s happening chemically?
A DNA nucleotide is made of three parts: a phosphate group, a deoxyribose sugar, and a nitrogenous base (here, thymine). During hydrolysis, water breaks the bonds linking the phosphate to the sugar and the sugar to the base, so each component is released as an individual molecule.
So, the thymine nucleotide → thymine + β-D-2-deoxyribose + phosphoric acid.
Mini breakdown (exam-style)
- Identify the nucleotide components
- Base: thymine (a pyrimidine)
* Sugar: 2-deoxyribose (β-D-2-deoxyribose)
* Phosphate: phosphoric acid (H₃PO₄)
- On complete hydrolysis you get:
- Free thymine
- Free 2-deoxyribose
- Free phosphoric acid
You can remember this as: nucleotide = base + sugar + phosphate → on hydrolysis, you get all three separately.
TL;DR:
When a nucleotide from DNA containing thymine is hydrolysed, it yields
thymine, β-D-2-deoxyribose, and phosphoric acid as the final products.
