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.
Does Complementary base pairing always pairs a purine with a pyrimidine?
Yes, complementary base pairing in DNA always pairs a purine (adenine or guanine) with a pyrimidine (thymine or cytosine). This specific pairing allows for the formation of hydrogen bonds between the bases, ensuring stability in the DNA double helix structure.
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.
How do the base pairing rule relate to chargaffs rules?
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.
Is thymine a purine?
The bases cytosine (C), thymine (T), and uracil (U), are pyrimidine derivatives. They have a six ringed structure.IN DNA, the purines adenine (A) and guanine (G) pair up with the pyrimidines thymine (T) and cytosine (C).Purines have a pyrimidine ring fused to an imidazole ring.As to the question: No, they do not. They are purines.

Where a purine base only pairs with a pyrimidine?
nitrogen

Is nitrogen a base?
A basic compound that contains nitrogen, such as a purine or pyrimidine. A basic compound that contains nitrogen, such as a purine or pyrimidine.
A particular sequence of parent DNA has five purine bases and two pyrimidine bases. According to base pairing rules, which of the following sequences could be formed during replication?
Chargaff's rule means that there should be the same number of purine and pyrimidine bases in DNA. The base-pairing rules mean 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.

Will a purine base bond with another purine?
no.because there is not enough space to bind two purine bases.
What base does cytosine base-pair with?
Cytosine, a pyrimidine (sugar) base, pairs with Guanine, a purine (nitrogen) base.
How does the diameter of DNA stay constant?
Adenine and Guanine are the purines and Cytosine and Thymine are the pyrimidines. Base pairng rules mean that Adenine always pairs with Thymine and Guanine always pairs with Cytosine. Thus each base pair is always a purine with a pyrimidine and hence they always have the same size -2nm.
Is thymine and guanine both pryimidine bases?
Thymine is a pyrimadine base. Guanine is a purine derivative.
