In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

Cytosine is one of the four main nitrogenous bases found in DNA and RNA, along with adenine (A), guanine (G), and thymine (T) or uracil (U). It is a pyrimidine derivative, meaning it has a single-ring ...
