In mitochondria UGA Codon act to specify
Correct answer: C. Tryptophan
- A. Arginine
- B. Glutamine
- C. Tryptophan
- D. Valine
Explanation
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. Tryptophan is an essential amino acid used to make proteins. The body does not make it, so it must be consumed in the diet. It is an amino acid needed for normal growth in infants and for the production and maintenance of the body's proteins, muscles, enzymes, and neurotransmitters. Tryptophan is encoded by a single codon UGG in most organisms. Since mitochondria are semi-autonomous organelles they can synthesise their proteins. Hence, tryptophan is encoded by the codon UGA in mitochondria.

About Ribonucleic Acid (RNA)
Ribonucleic acid is generally a single-stranded nucleic acid containing ribose and uracil instead of thymine. Coverage includes mRNA, tRNA and rRNA, complementary base pairing, transcription and translation, and the differences between RNA and DNA in structure, location and biological function.
