Answer:
Species C.
Explanation:
The bands of the unknown species most closely align with those in the Species C column.
The production of glucose.
Answer:
- The mRNA code for each type of amino acid is a sequence of <u>three</u> nucleotides, called a codon.
- mRNA codon that codes for the amino acid Phe es UUU.
Explanation:
The messenger RNA (mRNA) has in its structure sequences of 4 nucleotides adenine, uracil, guanine and cytosine. The possible combinations of these nucleotides to group into triplets is 64 codons to form 20 amino acids, from which it can be concluded:
- <em>An amino acid can be encoded by more than one codon.
</em>
- <em>From these combinations the three STOP codons are obtained.
</em>
A mRNA codon is a sequence of three nucleotides that serves to encode an amino acid.
Phenylalanine (Phe), according to the image, is formed with the UUU codon.
