In DNA replication, <u>adenine</u> pairs with thymine, and cytosine pairs with <u>guanine</u>.
In the field of science, DNA replication can be described as a process by which DNA makes copies of itself.
DNA is made of four nucleotide bases, deoxyribose sugar, and phosphate groups. The four nucleotide bases present in the DNA are adenine, guanine, thymine, and cytosine.
Adenine and guanine are nucleotide bases that have two carbon-nitrogen rings and are referred to as purines. Thymine and cytosine are made of one carbon-nitrogen ring and are referred to as pyrimidines. In the DNA, adenine pairs with thymine, and cytosine pairs with guanine.
