Explanation:
The process which is responsible during bone formation in equally in initial and later stages of remodelling, they are the bigger cells which are responsible for the synthesis and mineralisation  of bone. Osteocytes are the rich in cells in the bone tissue, which is helpful in detection of the mechanical loading, also manages the in bone formation and bone resorption. Osteoclast are cells that disintegrate the bone to start normal bone remodelling and also contemplate bone loss in pathologic condition by growing its resorptive capacity.

Answer: Nucleic acids 
Explanation:
Nucleic acids are biologically occuring polynucleotides in which the nuclotides residues are linked in a specific sequence by phosphodiester bonds. 
The two types of nucleic acids are DNA which is double stranded and serves as the usual carrier of genetic information while RNA which is single stranded serves a carriers of genetic information in some viruses only.
