Is thymine single ringed?
1, thymine and cytosine are pyrimidines (1 ring). Purines (adenine and guanine) have 2 rings.
The DNA molecule has four different kinds of these?
The DNA molecule has four different kinds of nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides combine in specific sequences to form the genetic code that determines an organism's traits.
What are the four components of a double helix?
Since the 4 bases are composed of 2 purines (adenine and guanine) and 2 pyrimidines (cytosine and thymine), 1 purine is bonded to 1 pyrimidine (e.g. guanine-cytosine; adenine-thymine). And the bond or linkage between this purine and pyrimidine is because of HYDROGEN BONDING.
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 is the structure of a nucleotide in a DNA molecule?
A nucleotide consists of three components: 1. A 5-carbon sugar (deoxyribose for DNA or ribose for RNA) 2. A nitrogenous base (adenine, cytosine guanine and thymine (or uracil in RNA) 3. A phosphate group

What is a pyrimidine in biology?
Pyrimidines are single ringed aromatic structures that make up 3 of the basic building blocks of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). Exampes include cytosine, thymine and uracil.
