∙ 15y agoI presume you are talking about the 4 heterocyclic bases in DNA. Two, cytosine and thymine, are based on pyrimidine and the other two, guanine and adenine, are based on purine.

The DNA molecule has four different kinds of these?
DNA molecules have four different kinds of bases. These bases pair up with one another in order to make DNA.
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 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 are the complementary base-pairing rules for biology?
In DNA, Adenine bonds with Thymine, Cytosine bonds with Guanine. In RNA, Thymine is replaced with Uracil (bases capitalized for easy emphasis/reference, not grammar.) Purines and Pyrimidines are two families of Nitrogenous bases. In DNA: Adenine and Guanine : Purines Cytosine and Thymine: Pyrimidines Adenine bonds with Thymine and Guanine bonds with Cytosine. A&T have 2 hydrogen bonds and G&C have 3 hydrogen bonds.
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).

How many resonance structures of pyrimidines are there?
2

Is berylium a metal nonmetal or metalloid?
Beryllium is a metal. It belongs to alkali metal group or group 2.
What is the group and the period of oxygen?
Oxygen belongs to the chalcogens family.
What family does tin and neon belong in?
Tin belongs to group 14, carbon family, period 5. Neon belongs to group 18, noble gases, period 2.
What is the prediction of valence electrons for barium?
Barium belongs to Group 2, so there are 2 valence electrons
What is the location of neon?
Neon is a noble gas and belongs to group 18 and period 2
What is Magnesium's classification Nonmetal Metal or Metalloid?
Magnesium is a metal. It belongs to group 2.
