Answer:
B). The double blind procedure.
Explanation:
'The double blind procedure' is demonstrated as the procedure or method of experiment in which both the experimenter as well as the subjects or participants of the experiment are 'blind to' or 'unaware' of the crucial/significant aspects like hypothesis of the experiment
As per the question, the 'double blind procedure' is being employed by the investigators as neither the subject of the experiment nor the experimenter know about the 'experiment containing aspirin or mere placebos' which would help in producing the objective and unbiased deductions. Thus, <u>option B</u> is the correct answer.
Disulfide bridges can be found in tertiary and quaternary structure levels of protein organization.
<h3>
What does a disulfide bridge in a protein do and what is its function?</h3><h3>
</h3>
Disulfide bonds or S-S bonds are other names for disulfide bridges. The establishment of these covalent bonds, which are formed between the sulfur atoms of two cysteine amino acids, stabilizes the tertiary and higher-order structure of proteins.
A frequent method utilized by nature to stabilize many proteins is the formation of disulfide bridges. These disulfide linkages are frequently observed in extracellular proteins that cells produce. The endoplasmic reticulum, an organelle, is where disulfide bridges are formed in eukaryotic species. When numerous proteins enter the secretory route for folding, disulfide linkages are formed between cysteine residues.
