Although the base pairing between two strands of DNA in a DNA molecule can be thousands to millions of base pairs long, base pairing in an RNA molecule is limited to short stretches of nucleotides in the same molecule or between two RNA molecules.
Complementary. The base pairs in DNA always follow a specific pairing rule (A with T, and C with G), which means that the sequence of bases on one strand determines the sequence on the other, making them complementary.
Complementary base pairing in DNA replication ensures accurate copying of the genetic information. During replication, the enzyme DNA polymerase adds complementary nucleotides to the template strand based on the base pairing rules (A with T, C with G). This results in two identical daughter DNA molecules.
In RNA, the unique complementary base pairing is between adenine (A) and uracil (U), and between guanine (G) and cytosine (C).
In DNA, adenine pairs with thymine and cytosine pairs with guanine through hydrogen bonding. This complementary base pairing allows for accurate DNA replication during cell division.
complementary nucleotides
Complementary base pairing takes place between nucleotide molecules in DNA, specifically between adenine (A) and thymine (T), and between guanine (G) and cytosine (C).
Complementary base pairing in genetics refers to the specific pairing of nucleotide bases in DNA molecules. Adenine pairs with thymine, and guanine pairs with cytosine. This pairing is essential for DNA replication and the transmission of genetic information.
Complementary base pairing is the specific bonding between adenine and thymine, and between cytosine and guanine in DNA molecules. This pairing ensures that the two strands of DNA are held together in a stable double helix structure. The hydrogen bonds formed between the complementary base pairs contribute to the overall stability of the DNA molecule.
Why is complementary base pairing crucial for life?
guanine pairing with cytosine
Complementary. The base pairs in DNA always follow a specific pairing rule (A with T, and C with G), which means that the sequence of bases on one strand determines the sequence on the other, making them complementary.

In RNA, the unique complementary base pairing is between adenine (A) and uracil (U), and between cytosine (C) and guanine (G).
Complementary base pairing in DNA-DNA pairing involves adenine (A) pairing with thymine (T) and cytosine (C) with guanine (G), following the rules of Watson-Crick base pairing. In DNA-mRNA pairing, uracil (U) replaces thymine, so adenine (A) pairs with uracil (U) in mRNA instead of thymine (T).
In RNA, the unique complementary base pairing is between adenine (A) and uracil (U), and between guanine (G) and cytosine (C).
