The structure and function of DNA RNA and ATP.

DNA (deoxynucleic acid).
Monomers are nucleotides, which consist of 1) phosphoric acid residue, 2) deoxyribose, 3) nitrogenous quenching. which can be represented by one of 4 (adenine, guanine, thymine, cytosine)
DNA functions – stores and transmits hereditary information about the primary structure of the protein.

RNA (Ribonucleic Acid)
Monomers are nucleotides composed of:
1) The remainder of phosphoric acid.
2) ribose
3) nitrogenous base. one of 4 (uracil, guanine, adenine, cytosine)
There are three types of RNA, each with its own function.
1) i-RNA (informational) function: transfers information from DNA to the site of protein synthesis.
2) t-RNA (transport) function: transfers amino acids to the site of protein assembly.
3) Ribosomal – RNA. Functions: protein synthesis, controls the connection of m-RNA with the active center of ribosomes.
ATP (adenine triphosphoric acid.
Consists of adenine, ribose and three phosphorus residues.
When a bond is broken into molecules, 40 kJ of energy is formed.
