1. (4 points) Given that the average molecular weight of an amino acid is 110 daltons (Da), determine the following. Remember to convert between daltons and kilodaltons (kDa) where necessary. Each of your answers must be numerically correct and expressed in proper units (1 pt) and show how the value was arrived at using the amino acid molecular weight above (1 pt) for you to receive full credit. A. A molecule of human a-tubulin has a molecular weight of 50.1...

Assume you were given a mixture consisting of one molecule each of all possible sequences of a smallish protein of molecular weight 4800 daltons. If the average molecular weight of an amino acid is, say, 120 daltons, how much would the sample weigh? How big a container would you need to hold it? What does this calculation tell you about the fraction of possible proteins that are currently in use by living organisms (the average molecular weight of proteins is...

An alternating copolymer is known to have a number-average molecular weight of 250,000 g/mol and a number-average degree of polymerization of 3406. One of the alternating mers is polystyrene which has a molecular weight of 105_g/mol. Given that the molecular weight of polypropylene is 42 g/mol and that of polyvinyl chloride is 61.5 g/mol, Which of them is the other alternating mer?
