Answer:
Here is a model showing what would happen if poison blocked our cell ability to make tRNA:

tRNA is a type of RNA that is involved in protein synthesis. It helps to carry amino acids to the ribosome, where they are assembled into proteins. If poison blocked our cell ability to make tRNA, it would prevent us from making proteins. This would lead to a variety of health problems, including:
* Muscle weakness
* Weight loss
* Fatigue
* Hair loss
* Skin problems
* Infections
* Death
In severe cases, blocking tRNA production can be fatal.
Here is a more detailed explanation of how tRNA works:
When a cell needs to make a protein, it first reads the DNA code for that protein. This code is transcribed into messenger RNA (mRNA). The mRNA is then translated into a protein by the ribosome.
The ribosome reads the mRNA codon by codon. Each codon is a sequence of three nucleotides that codes for an amino acid. The ribosome uses tRNA to bring the correct amino acid to the ribosome for each codon.
The tRNA molecule has an anticodon that matches the codon on the mRNA. The anticodon is a sequence of three nucleotides that is complementary to the codon on the mRNA.
The tRNA molecule binds to the ribosome at the codon that it matches. The amino acid that is attached to the tRNA is then added to the growing protein chain.
This process continues until all of the codons on the mRNA have been translated. The ribosome then releases the protein chain.
If poison blocked our cell ability to make tRNA, it would prevent the ribosome from getting the correct amino acids for each codon. This would result in the production of faulty proteins. These faulty proteins could damage the cell or even kill it.
