Which nucleotide are purines and which are pyrimidine?
Adenine and guanine are purines, while cytosine, thymine, and uracil are pyrimidines.
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.
Name the four nitrogen bases?
There are 4 nitrogenous bases found in DNA; Cytosine, Adenine, Guanine, and Thymine. Cytosine pairs with Guanine, and Thymine pairs with Adenine. *In RNA, Uracil replaces Thymine, therefore Adenine pairs with Uracil, in RNA.*
How are four bases paired in a molecule DNA?
Adenine(purine)=========thymine(pyrimidine)Guanine(purine)----------------cytosine(pyrimidine)
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).
What are the pyrimidine bases of RNA?
Thymine and cytosine are the pyrimidine bases of DNA. Uracil is the pyrimidine base which replaces thymine in RNA.
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.
Two nitrogenous bases known as purines are?
The two nitrogenous bases known as purines are adenine and guanine. They are found in DNA and RNA molecules, where they pair with thymine and cytosine (in DNA) or uracil and cytosine (in RNA), respectively.
Why are guanine and cytosine and they and adenine useful in the DNA molecules?
Guanine is a purine and Cytosine is a pyrimidine. They are nucleotides that pair together. The two are useful in DNA molecules because they pair together, along with Adenine and Thymine, which build a double helix. Guanine, Adenine, Thymine, and Cytosine are all nitrogenous bases.
What are the two Purines in DNA?
two of the bases are purines- adenine and guanine.
What are the bases of a DNA molecule?
The bases of a DNA molecule are adenine (A), thymine (T), cytosine (C), and guanine (G). They are the building blocks that pair up to form the rungs of the DNA double helix structure, with A pairing with T and C pairing with G.
What are the complimentary base paring?
Complementary base pairing refers to the specific hydrogen bonding between adenine (A) and thymine (T), and between cytosine (C) and guanine (G) in DNA molecules. These pairings are essential for maintaining the double-stranded structure of DNA and are key in the process of DNA replication and transcription.
