What are the complementary base pairs?

Complementary base pairing is the phenomenon where in DNA guanine always hydrogen bonds to cytosine and adenine always binds to thymine. The bond between guanine and cytosine shares three hydrogen bonds compared to the A-T bond which always shares two hydrogen bonds.

Regarding this, what are the complementary base pairs that form in DNA?

Each nucleotide base can hydrogen-bond with a specific partner base in a process known as complementary base pairing: Cytosine forms three hydrogen bonds with guanine, and adenine forms two hydrogen bonds with thymine. These hydrogen-bonded nitrogenous bases are often referred to as base pairs.

Also Know, what are the base pairing rules? The rules of base pairing (or nucleotide pairing) are:

  • A with T: the purine adenine (A) always pairs with. the pyrimidine thymine (T)
  • C with G: the pyrimidine cytosine (C) always pairs with. the purine guanine (G)

Also to know is, what are the 4 base pairs of DNA?

Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

What is complementary base pairing quizlet?

The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds.
