Answer: Prokaryotes lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found during a central a part of the cell called the nucleoid. The plasma membrane of a prokaryote acts as an additional layer of protection, helps maintain cell shape, and prevents dehydration.

Closing the stomata, or stoma, on the underside of the leaves in order to reduce water loss through the stoma during transpiration.
Answer:
tRNA molecules bring a specific <u>amino acid</u> to the ribosome, according to the <u>mRNA codon</u>.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
The function of tRNA depends on the complementarity that exists between the mRNA codon and the anti-codon tRNA, in such a way that
:
- <em>The pattern in the amino acid sequence of a protein is indicated by mRNA
</em>
- <em>tRNA has a complementary anticodon, so it will only bring the specific amino acid that the codon encodes.</em>
In general terms, each mRNA molecule possesses the genetic code that indicates the amino acid sequence of a protein, and tRNA helps bring those amino acids to the ribosome for synthesis to occur.
