The molecular iodine (12) in betadine is susceptible to decomposition if exposed to direct sunlight, which lowers the concentration of I2 solution. After performing the standardization step in home experiment 9, a student leaves their betadine solution in direct sunlight for several hours before coming back to perform the titration of ascorbic acid in orange juice. Assuming that the concentration of l2 is reduced by the sunlight, how would this affect the measured value of the concentration of ascorbic acid in the orange juice? The measured concentration of ascorbic acid would be higher The measured concentration of ascorbic acid would be lower There is not enough information to determine the affect on the measured concentration of ascorbic acid The measured concentration of ascorbic acid would be unaffected O O

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.
