cytosín
Cytosine is one of the four main nucleobases found in DNA and RNA. It is a pyrimidine derivative, meaning it has a heterocyclic aromatic organic compound with two nitrogen atoms at positions 1 and 3 of the six-member ring. Cytosine is represented by the letter C and plays a crucial role in the genetic code.
In DNA, cytosine always pairs with guanine through three hydrogen bonds. This specific base pairing is fundamental
Cytosine can undergo deamination, a chemical reaction where an amino group is removed. This process can convert
