Cytosine and thymine are the pyrimidine bases in DNA.
Thymine and cytosine are the pyrimidine bases of DNA. Uracil is the pyrimidine base which replaces thymine in RNA.
Thymine
DNA does in fact contain cytosine. This is one of the 4 nucleic acids that are found inside of DNA.
Is a DNA lesion caused by UV light irradiation. When DNA strand is exposed to UV light, adjacent pyrimidine residues on a DNA strand can become covalently linked. Such pyrimidine dimers cannot fit into a double helix, and so replication and gene expression are blocked until the lesion is removed. This kind of lesions are common and therefore DNA is continually being repaired by specific enzymes that make the job.
Thymine.
Cytosine is the pyrimidine that bonds to the purine Guanine in both DNA and Rna.
Uracil
Cytosine and thymine are the pyrimidine bases in DNA.

a base containing nitrogen that is found in RNA (but not in DNA) and derived from pyrimidine; pairs with adenine
1. Purines 2. Pyrimidine
Adenine(purine)=========thymine(pyrimidine)Guanine(purine)----------------cytosine(pyrimidine)
Thymine and Cytosine are the pyrimidine nucleotides of DNA, while Adenine and Guanine are the purine structures.
One difference between DNA and RNA is that DNA has a nitrogen base pyrimidine thymine that connects with purine adenine. In RNA, thymine is replaced by another pyrimidine called uracil.
