Several calibration curves were created for a series of protein standards of known molecular mass using molecular exclusion columns with different pore sizes. Which pore size should be used to perform molecular exclusion chromatography of proteins with a molecular mass near 10,000? 10 μm 5 nm 10 nm 1 pm 100 µm 50 nm 100 nm log (molecular mass) 7- 5mm 5.0 6.0 100 m Lum 10 m 7.0 8.0 9.0 100 um Elution volume (ml) 10.0 11.0 12.0
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.
