Answer:
agricultural aspect of how the Mayans grew their crops.
Explanation:
Answer:
1. The cells will encounter with nitrogen stress, will cease the production of monoclonal antibodies and will die eventually if the fused cells are transferred to a growth medium, which is devoid of nitrogen. The amino acids and the DNA, all comprise nitrogen as a basic building block.
In the case of the nitrogen is not present, the replication of DNA will get influenced, thus, influencing the production of proteins due to defective amino acids that will eventually result in the death of cell.
2. Nitrogen is present in the biological macromolecules like amino acids and DNA. The composition of an amino acid is not complete in the absence of nitrogen. In the case of DNA, the bases, that is, the pyrimidines and purines all comprise nitrogen in their fundamental composition.
The amino acids in combination produce proteins, the antibodies are proteins. Thus, if the formation of amino acids does not take place, the formation of monoclonal antibodies will also get ceased. Also, for the replication of DNA and transcription process, there are requirements of dNTPs and rNTPs, which also constitute nitrogen fundamentally. Hence, in the absence of nitrogen the cell will die.
