Sytosiiniemäksiin

Sytosiiniemäksiin refers to cytosine bases, which are one of the four nucleobases in the nucleic acids DNA and RNA. Cytosine 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. In DNA, cytosine (C) pairs with guanine (G) through three hydrogen bonds. In RNA, cytosine also pairs with guanine. The molecular formula for cytosine is C4H5N3O. Cytosine plays a crucial role in genetic information storage and transmission. It is also involved in various biological processes beyond its role in DNA and RNA. Chemical modifications of cytosine, such as methylation, can occur and have significant regulatory functions in gene expression, particularly in epigenetics. These modifications can influence DNA structure and protein binding, thereby impacting cellular development and disease.
