The A260/A280 ratio method estimates protein ________________ by measuring the absorbance maximum at 280nm caused by the amino a
Jet001 [13]

Answer:

By way of introduction, A260/A280 ratio is use to measure Protein Contamination. This procedure was first described to measure protein purity in the presence of nucleic acids. However it is now commonly used to assess protein contamination of DNA. The method to determine the concentration of protein contamination by using A260/280 ratio method is well explained below by filling in the missing words.

Explanation:

The A260/A280 ratio method estimates protein __purity___ by measuring the absorbance maximum at 280nm caused by the amino acids__cytosine___, ____Adenine____, and ___Guanine_________ Since ___Spectrophotometer____ also absorbs in the UV range, we can correct for this contaminate by measuring the absorbance maximum at ____260nm______ and using the following equation: Concentration (µg/ml) = (A260 reading – A320 reading) × dilution factor × 50µg/ml___ When extrapolated from a standard curve, the Bradford data indicates the amount (in _ug__ ) of __unknown ___ protein found in a sample. If you know the volume of sample that was added to the assay then you can calculate the protein ____concentration ___ of the sample. The coomassie blue dye in the Bradford assay specifically binds primary ¬¬___sulfonic___ and __positive amines__ groups of the amino acid side groups of the proteins. The more the dye binds to the sample, the _anionic_ the blue color will be, and the absorbance at 595¬nm will be_shifted Amax___. A sample with an unusually __protein___ number of ___280nm of Tyrosine __ [give a specific example] amino acids will underestimate the total amount of protein present in the sample.

Can one process go on continually without the other? Be sure to support your answer with what you have learned about each proces
Damm [24]
I don't think one process can go on continuously without the other. Because during the photosynthesis carbon dioxide is necessary along with sunlight, water to make glucose and oxygen. Without oxygen we won't survive if we don't survive then there will be no carbon dioxide. Aerobic respiration is when you take in oxygen made by plants in the process of photosynthesis as the product of aerobic respiration we breath out carbon dioxide which plants use to make glucose and oxygen.
