Answer:

4 amino acids.

Explanation:

To become translated into protein, a sequence is read in triplets called codons.

Each codon that codes for an amino acid is made up of 3 nucleotides.

Therefore, a sequence of 15 nucleotides would be translated into a polypeptide that is made up of 5 amino acids. (15 divided by 3 = 5)

However, we are told that there is a stop codon at the end of this sequence.

A stop codon is a specialised codon that does not code for an amino acid, but tells the protein machinery that the polypeptide is complete.

Therefore, the polypeptide would have 5-1 amino acids, which corresponds to 4 amino acids.

Gary doesn’t like yard work but he notices that the leaves on his lawn are starting to break down. What process is occurring her
Anettt [7]
The process is decomposition.

Decomposition is a process by which organic substances, like leaves, are broken down into simpler matter. A lot of different types of organisms, called the decomposers, will consume the organic substances(like dead plants, dead animals) and continue an essential part of the nutrient cycle. This is important for recycling the organic matter that occupies space in the biosphere.
