Question

As part of your undergraduate research project, you are characterizing three polypeptides of approximately equal molecular weight from human plasma. Using various physical techniques, you have established that in their native states one of the polypeptides is a monomeric, cigar-shaped molecule, the second is monomeric and approximately spherical, and the third is the subunit of a teiramer of identical subunits. Another student (Lisa, who you arc working with on the project) in the research group has determined the amino acid compositions of the three proteins. However, when Lisa brings you the data, shown in the table below, you are greatly upset to discover that she failed to note which composition corresponds to which protein. Another student. Alison, working in the lab (on another project) tells you that you should simply deduce which is which from the amino acid compositions themselves. Lisa is sure that Alison is wrong. Should you take Alison's advice? If you decide to do so, which composition would you assign to which protein, and why?

Answer 1

You must not follow Alisson's advice.

Step-by-step explanation:

The data analyzed by Lisa are shown in the figure attached below. When analyzing this data, you will see that it is not possible to deduce which protein is which efficiently, since the data is not enough to show the shape of the proteins.

To deduce which protein is which, from these data, would make the research imprecise, since there were no tangible justifications capable of justifying the deduction.

In a scientific research, all statements expressed must be scientifically justified and proven, in which case deductions cannot be part of the project.
