natita [175]

Answer:

The correct order of the numbers to place the protein creation steps is:

3, 1, 4, 2, 5.

Second, (1) the information from the DNA is transcribed from the DNA to the mRNA. Third, (4) the tRNA anticodon carried the amino acid that complements the mRNA codon. Fourth, (2) the mRNA leaves the nucleus, Fifth, (5) the chain of aminoacid forms a protein. Thus, that is why our proposed order is the correct question.
