The answer is the last one
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. ... The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.
Based on this observation you would predict that the MISFOLDED BETA AMYLOID PROTEINS COULD NOT BE REFOLDED BY THE CHAPERONE PROTEINS.
Chaperon proteins are proteins which assist newly formed proteins to form correctly. A protein that is already mis-folded can not be refolded by the chaperone proteins.
It’s the letter C.................
The sulphur would lable the capsule and the phosphorous the nucleic acid.
<h3><u>Explanation</u>:</h3>
Hershey and Chase experiment included growing of the pages in two batches, one in presence of 35S and other in presence of 32P. They then infected bacterial cells with these phages, cleaned them and then centrifuge the cells to isolate the marked elements in bacterial cells.
This was done to isolate which part of the phage is actually infective. Sulphur being a part of the proteins will mark the capsule whereas DNA having the phosphate bridges will be marked by 32P.
