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. Hopfully (whom who needs help on homework ;)lol)
What else can I help you with?
Purine bases have what kind of structure?
Purine bases have a double-ring structure, consisting of a pyrimidine ring fused to an imidazole ring. Adenine and guanine are the two purine bases found in DNA and RNA molecules.
What are the elements of a nitrogenous 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.
What are the DNA pyrimidines?
Thymine and cytosine are the pyrimidine bases of DNA. Uracil is the pyrimidine base which replaces thymine in RNA.
What bond holds purine bases and pyrimidine bases together?
Hydrogen bonds hold purine bases (adenine and guanine) and pyrimidine bases (cytosine, thymine, and uracil) together in DNA and RNA molecules. These hydrogen bonds form between specific pairs of bases, with adenine always pairing with thymine (or uracil in RNA) and guanine always pairing with cytosine.
Can purines pair with other purines?
No, purines cannot pair with other purines in DNA or RNA. Purines always pair with pyrimidines through complementary base pairing to maintain the double-stranded structure of DNA. In DNA, adenine (a purine) pairs with thymine (a pyrimidine) and guanine (a purine) pairs with cytosine (a pyrimidine).
Pyrimidine base found in DNA and RNA?
Cytosine is the pyrimidine that bonds to the purine Guanine in both DNA and Rna.
What are DNA and RNA similarities?
DNA and RNA contain purine and pyrimidine nitrogenous bases, one benzoic acid radicle and one pentose.
What are the purine bases and pyrimidine bases?
The purine bases are adenine and guanine, while the pyrimidine bases are cytosine, thymine, and uracil. Purine bases have a double-ring structure, while pyrimidine bases have a single-ring structure. These nitrogenous bases are essential components of DNA and RNA molecules.
One DNA base not normally present in RNA is?
One difference between DNA and RNA is that DNA has a nitrogen base pyrimidine thymine that connects with purine adenine. In RNA, thymine is replaced by another pyrimidine called uracil.
Nitrogenous bases of the purine type?
In DNA cytosine and thymine are pyrimidine derivatives. Uracil (in RNA) is also a pyrimidine. Pyrimidines have only one 6-membered ring.
Does DNA or RNA have uracil?
purine. I remember cytosine, guamine, and uracil are pyrimindine because the word pyrimidine makes me think of the word pryamid and there are THREE pyrimidines which spell the word CUT :) hope that helps :)
What are the three pyrimidine bases?
There are 2 groups of nitrogen bases. These are Pyrimidine and Purine. In the Purine group, there are Adenine and Guanine, In the Pyrimidine group, there are Cytosine, Thymine(replaced by Uracil in RNA).
Purine bases have what kind of structure?
Purine bases have a double-ring structure, consisting of a pyrimidine ring fused to an imidazole ring. Adenine and guanine are the two purine bases found in DNA and RNA molecules.
Will a purine base bond with another purine?
no.because there is not enough space to bind two purine bases.
What are the elements of a nitrogenous 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.
What are the DNA pyrimidines?
Thymine and cytosine are the pyrimidine bases of DNA. Uracil is the pyrimidine base which replaces thymine in RNA.
What bond holds purine bases and pyrimidine bases together?
Hydrogen bonds hold purine bases (adenine and guanine) and pyrimidine bases (cytosine, thymine, and uracil) together in DNA and RNA molecules. These hydrogen bonds form between specific pairs of bases, with adenine always pairing with thymine (or uracil in RNA) and guanine always pairing with cytosine.
