Suffering the impact of swarms of locusts, a farmer uses an airplane to spray an insecticide over 1,500 acres of his corn field.
Crazy boy [7]

Answer:

C. a chemical treatment.

Explanation:

In this case we would be talking about a chemical treatment, since the application of an artificial compound is made, and it is not clarified that it was "ecofriendly".

On the other hand, the question clarifies that the farmer is suffering from the plague. This indicates that he is not preventing it (Integrated pest management), he is treating it.

Finally, it should not be considered as an agronomic treatment, since no real modifications are being made to the way the field is managed.

A single codon is used to signal the beginning of protein synthesis. It is commonly called the START CODON. Locate the start cod
Artemon [7]

About the question:

You will find the chart in the attached files

Answer:

The strat codon is AUG  

Explanation:

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named <em>codons </em>in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

  • The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.
  • The end codons are UAA, UAG, UGA.
