Base pairs There are chemical cross-links between the two strands in DNA, formed by pairs of bases. They always pair up in a particular way, called complementary base pairing: thymine pairs with adenine (T–A) guanine pairs with cytosine (G–C)

Complementary base pairing is the phenomenon where in DNA, guanine always binds to cytosine and adenine always binds to thymine.

”’complementary base pairing. The standard arrangement of bases in nucleotides in relation to their opposite pairing, such as thymine being paired with adenine and cytosine paired with guanine.

Complementary base pairing is important in DNA as it allows the base pairs to be arranged in the most energetically favourable way; it is essential in forming the helical structure of DNA. It is also important in replication as it allows semiconservative replication.

DNA transcription uses complementary base pairing of adenine, thymine, cytosine and guanine (on the DNA) to uracil, adenine, guanine and cytosine (on the nRNA) respectively.

8 Translation depends on complementary base pairing between codons on mRNA and anticodons on tRNA. Every set of three nucleotides on the mRNA is called a codon and each codon is complementary to an anticodon on the tRNA strand.

The part of translation that depends on the same base pairing rule found in transcription and DNA replication happens when anti-codons in tRNA are matched with complementary codons inmRNA in the ribosome….

Chargaff’s rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa.

Complementary base pairing is very important in the conservation of the base sequence of DNA. This is because adenine always pairs up with thymine and guanine always pairs up with cytosine. Therefore, complementary base pairing has a big role in the conservation of the base sequence of DNA.

New cells are continuously forming in the body through the process of cell division. For this to happen, the DNA in a dividing cell must be copied in a process known as replication. The complementary base pairing of the double helix provides a ready model for how genetic replication occurs.

DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .

In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
