c and t are pyrimidines, as is U
Thymine is a pyrimadine base. Guanine is a purine derivative.
A nucleotide is composed of a Nitrogenous base, a phosphate, and a ribose sugar.
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.
Adenine and Guanine are the purines and Cytosine and Thymine are the pyrimidines. Base pairng rules mean that Adenine always pairs with Thymine and Guanine always pairs with Cytosine. Thus each base pair is always a purine with a pyrimidine and hence they always have the same size -2nm.
