Why does Purine not bind with Purine in DNA?

Updated: 5/20/2024

Yes! Purines in DNA are Adenosine (A) and Guanine (G). Pyrimidines in DNA are Cytosine (C) and Thymine). In DNA, A bonds with T using 2 H-bonds (Hydrogen bonds) and C bonds with G using 3 H-bonds.

Purine bases (adenine and guanine) do not bind with each other because their structural arrangement does not allow for stable hydrogen bonding interactions. The size and shape of purine bases prevent them from forming the complementary hydrogen bonding patterns required for stable base pairing in DNA.

The shape of a Purine forces in a Purine-Purine pairing for the Hydrogen molecules to be to close to one another. This leads to electrostatic repulsion forcing the pair apart.

When purine base only pairs with a pyrimidine?

This is a basic principle of DNA base pairing called Chargaff's rule. Adenine (purine) pairs with thymine (pyrimidine), while guanine (purine) pairs with cytosine (pyrimidine). This complementary base pairing is essential for the double-stranded structure of DNA.

A purine base that pairs with cytosine?

Adenine is the purine base that pairs with cytosine through hydrogen bonding in DNA. This base pairing is a key component of the complementary nature of DNA strands.

Purine base that pairs up with thymine and uracil?

Adenine is the purine base that pairs up with thymine in DNA and with uracil in RNA.

Number of purine bases in DNA molecule with nine base pairs?

There would be a total of six purine bases in a DNA molecule with nine base pairs. Purine bases include adenine (A) and guanine (G). Each base pair consists of one purine base and one pyrimidine base.

Does cytosine contain a purine?

No, cytosine is a pyrimidine base, not a purine. Purines are adenine and guanine, while pyrimidines are cytosine, thymine, and uracil.
