Answer:
Trypanosoma brucei
Explanation:
T. brucei is a unicellular eukaryotic parasite that causes sleeping sickness. This organism has an elongated body, central nucleus, only an elongated mitochondria housing the kinetoplast, where the mitochondrial DNA is located; It has a scourge that gives it motility. Its undulating cell membrane, as a result of flagellar movements, is covered with glycoproteins that elicit little immune reaction, allowing this parasite to go unnoticed.
This organism infects the host by evading the host's immune system by altering its surface proteins with each generation.
The process of genetic engineering has been utilized to create this drug.
Genetic engineering is the artificial modification of DNA or other nucleic acid molecules in order to alter an organism’s characteristics in a certain way using biotechnology. Genetic engineering is used by scientists to improve or change the genetic makeup of an individual organism and it involves the transfer of genes to create ameliorate organisms.
The chart very nicely lays out the amino acid each codon corresponds to. You're looking for "trp" in the chart, which only appears once, beside the UGG codon. Therefore, only one codon codes for tryptophan.
