Thymine (T): Thymine is a pyrimidine base found exclusively in DNA. It forms a complementary base pair with adenine (A) through hydrogen bonding. Uracil (U): Uracil is a pyrimidine base found ...

Structure of purines Purine biosynthesis is complex. The purine skeleton is a 6-membered pyrimidine ring fused to a 5-membered imidazole ring (See Figure 1). Each ring contains two nitrogen (N ...

Ultraviolet (UV) rays from sunlight can cause DNA damage that leads to skin aging and cancer. Fortunately, our bodies have a ...

DNA is composed of nucleobases represented by the letters A, T, G and C. They form the basis of the genetic code and are present in all living beings. But in a bacteriophage, another base ...

Abstract Ultraviolet-induced DNA lesions are removed by the nucleotide excision repair (NER) pathway. In global-genome NER (GG-NER), XPC-RAD23B ...

For example, the technique can be used to convert a cytosine (C) base to a thymine (T) base, both bases within the pyrimidine class (performed with a cytosine base editor, or CBE).
