Thymine is one of the four main nucleobases found in the nucleic acid DNA. It pairs with adenine.
Adenine (A): A component of DNA or RNA that forms a base pair with thymine (in DNA) or uracil (in RNA).
Deoxyribose Sugar: The sugar component present in each nucleotide that makes up DNA; it binds to both thymine and phosphate group to form part of the backbone structure.
DNA Replication: The process by which an entire double-stranded molecule of DNA creates two identical copies.
