Here are the essential concepts you must grasp in order to answer the question correctly.
Nucleotide Structure
Nucleotides are the building blocks of nucleic acids like DNA and RNA. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. Thymine and uracil are both nitrogenous bases, but they differ in their chemical structure, which influences their roles in DNA and RNA.

Base Pairing
Base pairing is a fundamental concept in molecular biology that describes how nitrogenous bases pair with each other to form the structure of DNA and RNA. In DNA, thymine pairs with adenine, while in RNA, uracil replaces thymine and pairs with adenine. This difference is crucial for understanding the stability and function of genetic material.

Function in Genetic Material
Thymine and uracil serve different functions in genetic material. Thymine is found exclusively in DNA, contributing to its stability and integrity, while uracil is present in RNA, where it plays a role in protein synthesis and gene expression. Understanding these functions helps clarify the distinct roles of DNA and RNA in biological systems.
