Adenine is an organic molecule found in DNA, ribonucleic acid (known as RNA) and adenosine triphosphate, better known as ATP.

Guanine

Guanine is a purine base found in DNA and RNA that binds exclusively with cytosine to form ribonucleosides called guanosine or deoxyribose to form deoxyguanosine.

Thymine

Thymine is a pyrimidine base found in DNA that binds to adenine.

Cytosine

Cytosine is a pyramid-shaped nitrogenous base that binds to guanine in RNA and DNA as nucleotides and functions as part of the genetic code.

Ossification is the process of bone tissue formation. Osteoblasts are responsible for the process of ossification. It begins when the fetus is three months old and goes on till 25 years of age. Upper limbs get ossified first, followed by lower limbs, sternum and vertebrae.

There are two types of ossification processes. When bone is directly developed using the primitive connective tissue (mesenchyme) it is called as  intramembranous ossification, while in endochondral ossification cartilage is used as a precursor.
