(B) 11,550 Da
1. (4 points) Given that the average molecular weight of an amino acid is 110 daltons...
assuming that amino acids in protein have an average molecular weight of 120 daltons, about how much does usherin protein weigh, show your calculations
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...

QUESTION 7 Consider the hypothetical gene show here. The gene coding sequence consists of 4 exons (shown in solid colors). The 5' UTR and 3' UTR are shown as striped boxes. 25 150 200 300 400 25 Based on the lengths of the exons, you should be able to calculate a rough estimate of the protein encoded by this gene, assuming that all 4 exons are translated and the protein does not undergo any significant processing (cleavage or chemical modifications)....

The sandard unknown proteins and the rabbit serum prins for this experimentarehe pre- tined to allow you to follow the portion during crophews Background Information A first step in the analysis of a protein in the molecular biology laboratory frequently involves determination of its sie or molecular weight. The molecular weight of a...
QUESTION 6 Assume you are studying a protein-coding gene, ACEX, which includes 4 exons as illustrated in the gene map below. The 5' UTR and 3' UTR segments are each 25 bp long. Exons 1 thru 4 are 100, 200, 300, 400 bp long, respectively. Each intron is 200 bp each. The locations of the relevant EcoRI sites within the ACEX locus are indicated, but the location of other restriction enzyme sites (like BamHI) are not shown." EcoRI probe EcoRI...
