Adenine pairs with thymine Guanine pairs with cytosine.
Base Pairing Rules
The rule used to join free nucleotides to the exposed bases of DNA is base pairing. Adenine pairs with thymine, and guanine pairs with cytosine through hydrogen bonding. This complementary base pairing ensures the accurate replication of DNA during cell division.
Watson and Crick came up with the base-pairing rule for nucleic acids using Chargaff's rule that in DNA the percentages of adenine and thymine are equal, and the percentages of guanine and cytosine are equal. Refer to the related link below.
DNA bases are always paired through hydrogen bonding. Adenine pairs with thymine, while cytosine pairs with guanine. This complementary base pairing ensures the stability and accuracy of DNA replication and transcription processes.

Adenine pairs with thymine Guanine pairs with cytosine.

Yes.;) Possibly.
According to the base pairing rule, cytosine always pairs with guanine in DNA and RNA. This pairing is due to the formation of three hydrogen bonds between the two nitrogenous bases, which helps maintain the stability of the DNA double helix structure.

A goes to U and G goes to C. DNA its A=T G=C.
mRNA makes a complimentary copy of the DNA molecule according to the base-pairing rule.
The base pairing rule ensures that during DNA replication, each base on one strand pairs with its complementary base on the other strand, forming an identical copy. This process maintains the genetic information in the original DNA molecule and results in the production of two identical DNA molecules.
The monomers in DNA, known as nucleotides, pair up through specific base pairing: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This base pairing rule was proposed by James Watson and Francis Crick in 1953, based on earlier research, including the work of Rosalind Franklin and Erwin Chargaff, who discovered the complementary nature of the nucleotide bases. This pairing is essential for the structure of the DNA double helix and for accurate DNA replication.
Chargaff's rule means that there should be the same number of purine and pyrimidine bases in DNA. The base pairing rules means that A always pairs with T, and G always pairs with C ie. a purine always pairs with a pyrimidine, so there must be the same number of both proving Chargaff's rule.
