The basic repeating unit of nucleic acids are known as nucleotides. A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base - (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.

Oxygen, a byproduct of the process, is released through these openings, along with water vapor in a process called transpiration.

Explanation:
Los fósiles se forman a través de varios tipos de fosilización: mineralización, carbonización, momificación, y fundición y moldes.
