How do you Calculate the ratio of purines to pyrimidines?
It should always be a 1:1 ratio
Nitrogen bases with only 1 ring are called?
Purines
What are the two nitrogen bases that are single ring structures?
Thymine is a single-ringed nitrogenous base.
What is The ratio of purine and pyrimidine in DNA and RNA?
Not necessarily, you are mixing up your terms. DNA and RNA are two different types of nucleic acids. Pyrimidines and purines are subsets of those nucleic acids. Let me show you an example: DNA is composed of deoxy A,T,C,G type nucleic acids, A and G are purines, T and C are pyrimidines. RNA is composed of (oxy) A,U,C,G type nucleic acids, A and G are purines, U and C are pyrimidines. The A and G purines in DNA and RNA are not the same since both DNA and RNA are intrinsically different (although their structures are similar). This goes the same for U,C and T. These will help you.

Why all organism have same ratio of base pair in DNA?
Organisms normally have equal amounts of the bases adenine and thymine (ratio of A:T = 1) and equal amounts of the bases cytosine and guanine (ratio C:G = 1). The reason is that there is specific base pairing ie adenine can only pair with thymine and cytosine can only pair with guanine. So in a DNA double helix, every adenine in one strand must be paired with a thymine in the other strand. Similarly, every cytosine in one strand must be paired with a guanine in the other strand. Each base pair consists of a purine and a pyrimidine. Adenine and guanine are purines and thymine and cytosine are pyrimidines. This relationship between purines and pyrimidines was discovered by Erwin Chargaff in the 1950's. See: http://en.wikipedia.org/wiki/DNA http://en.wikipedia.org/wiki/Chargaff%27s_rules
What is the relative percentage of purines to a pyrimidines in a DNA molecule?
1:1
How do you Calculate the ratio of purines to pyrimidines?
It should always be a 1:1 ratio
How are the structures of purines and pyrimidines different?
The main chemical structure difference in purines and pyrimidines is purines have a 5 sided C and N based ring as well as a 6 sided C and N based ring structure. Pyrimidines only have the 6 sided C and N based ring structure, also uracil(unmethylated) replaces thymine(methylated) as a pyrimidine in RNA.
Is thymine single ringed?
1, thymine and cytosine are pyrimidines (1 ring). Purines (adenine and guanine) have 2 rings.
Nitrogen bases with only 1 ring are called?
Purines
Which nucleotides are purines?
purines are double ringed nitrogenous bases of DNA and RNA including adenine and guanine. the three others are cytosine and thymine( uracil is present instead of thymine in RNA) are pyrimidines. 1.nitrogen is present at 1,3,7,9 positionin in purines.
What are the two nitrogen bases that are single ring structures?
Thymine is a single-ringed nitrogenous base.
How tall is Stewart Haney?
Stewart Haney is 5' 8 1/2".
What are the two kinds of nucleic acid's?
a There are two types of nucleic acids. Purines and Pyrimidines. Purine contains 1) Adenine 2) Guanine. Pyrimidines contains 1)Cytosine 2) Thymine 3)Uracil. Out of this Uracil replaces Thymine in RNA molecule. DNA contains 1) Adenine 2) Guanine 3)Cytosine 4)Thymine.
How many rings do pyrimidines have in their molecular structure?
1
What does purine mean?
A purine is a nucleotide in DNA that only has 1 ring.
