Answer:

A: serine, tryptophan, serine, valine

Step-by-step explanation:

Hi there!

Protein Synthesis is the process where proteins are created from DNA.

We are given the mRNA strand AGUUGGUCUGUA, as well as a provided chart

The mRNA strand is created out of nucleotides (each of the letters is one nucleotide in the code), which will code for a specific chain of amino acids, creating a protein.

Each amino acid is made up of 3 nucleotides. This sequence of 3 nucleotides is called a codon.

So we can break up the code into groups of 3, to make identifying the codons easier.

AGU UGG UCU GUA

Now we need to figure out which amino acid each codon codes for. Thankfully, we were given a chart that can help us with that.

The chart is read where the first base is on the left, and is vertical. The second base is in the center, yet is horizontal. The third base is on the right, and is also vertical.

Let's start with the first codon, which is AGU

The first base is A. The second base is G, and the third base is U. So the first amino acid is serine (ser)

The second codon is UGG.

The first base is U, the second base is G, and the third base is G. So the second amino acid is tryptophan (trp)

The third codon is UCU

The first base is U, the second base is C, and the third base is U. So the third amino acid is serine (ser)

The fourth codon is GUA

The first base is G, the second base is U, and the third base is A. So the fourth amino acid is valine (val).

That means the amino acid sequence from the mRNA code is: serine, tryptophan, serine, valine. The answer is A

Hope this helps!
