Lewis structures, also known as electron-dot or electron-dot diagrams, are diagrams showing the bonding between a molecule's atoms and the lone pairs of electrons that may occur in the molecule. Also known by its IUPAC name, 6-amino-1H-pyrimidine-2-one, cytosine is one of three pyrimidine bases, with thymine and uracil constituting the remaining two. Omissions? https://www.britannica.com/science/cytosine. When this occurs in DNA, the DNA sequence is corrected by repair mechanisms. It's a pyrimidine nucleobase, pyrimidone, and aminopyrimidine all rolled into one. Since DNA does not contain uracil, so the uracil formed due to the deamination of cytosine is identified as foreign and is removed by a repair system. When cytosine is on one strand of a nucleic acid, the other strand will contain a guanine to match. Enter the formula of the molecule in the field provided for it. Due to these three hydrogen bonds, the cytosine-guanine base pair has an overall higher boiling point and greater bond strength than the adenine-thymine base pair.
