Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.

c) Jean-François is studying a specific protein in a research laboratory. In previous experin
he observed that this protein seems to function as a receptor protein on the surface of cells
recognizes a specific hormone involved in cell-cell communication.
Jean-François prepares his final experiment, but makes a mistake in calculating how mucl
add to one of his solutions to get the correct pH. He performs the experiment, and much te
surprise, he observes that his protein no longer seems to be recognizing the hormone anyr
he had observed in previous experiments.
Propose a hypothesis that briefly explains (2-3 sentences) why the results of Jean-Françoi
experiment have changed.
Jean-François ex periment have changed because the
pit denatures the protein structure, Because mast a
