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.
How many rings do pyrimidines have?
Pyrimidines have a single ring and are part of the basic building blocks for RNA and DNA.
What is the difference between purines and pyramidines?
Purines (adenine and guanine) are larger, double-ring nitrogenous bases found in DNA and RNA, while pyramidines (cytosine, thymine, and uracil) are smaller, single-ring bases. Purines always pair with pyramidines in DNA strands to maintain the proper structure of the double helix.
What is the structure of a prokaryotic cell DNA?
A single large ring chromosome and many tiny ring plasmids.
Carbon ring structure of DNA and RNA that contains one or more atoms of nitrogen?
Carbon ring structures found in DNA or RNA that contains one or more atoms of nitrogen are called nitrogenous bases. There are five types of nitrogenous bases: Adenine, Thymine, Cytosine, Guanine and Uracil
Is mitochondria made up of cytoplasm?
Mitocondria have the same structure as bacteria: outer lipid bilayer membrane, cytoplasm, large ring shaped DNA chromosome, small ring shaped DNA plasmids.
What is the shape of the sugar found in the DNA?
The sugar found in DNA, deoxyribose, is a five-carbon sugar with a five-sided ring in the shape of a pentagon.

In a eukaryotic cell what is one of the structures in the nucleus that is made up of DNA and protein in a prokaryotic cell is the main ring of DNA?
In a eukaryotic cell, the structure made up of DNA and proteins in the nucleus is the chromosome. In prokaryotic cells, the main ring of DNA is called the nucleoid, which lacks a membrane-bound nucleus.
What are pyrimadines an purines?
Pyrimidines (cytosine, thymine, uracil) are nitrogenous bases with a single-ring structure found in DNA and RNA. Purines (adenine, guanine) are nitrogenous bases with a double-ring structure also found in DNA and RNA. They form the building blocks for nucleic acids.
Does cytosine contain a purine?
DNA does in fact contain cytosine. This is one of the 4 nucleic acids that are found inside of DNA.
A chromosome is the ring of DNA in what kind of cell?
The prokaryote cell. Archaebacteria and eubacteria have their DNA in a ring and also carry extra DNA sometimes, also arranged in a ring.
