Question

Use the codon table to determine which mrna triplets code for the amino acid cysteine, cys.

Answer 1

Cysteine (Cys) is a semi-essential proteinogenic amino acid. It is coded by the codons UGU and UGC. 

It is normally found in most high-protein foods from animal sources such as meat, eggs, and dairy, and from plant sources such as oats, garlic, onions, brussels sprout, sprouted lentils, broccoli, and many more.

In the human body under normal physiological conditions, this amino acid can usually be produced provided that sufficient amounts of methionine is available. Although it is non-essential, it may be necessary for infants, the elderly, and those who suffer from metabolic diseases or malabsorption syndromes. 

Answer 2

The RNA or ribonucleic acid triplets for the amino acid cysteine are TGT and TGC.

Further Explanation:

A codon refers to the sequence of the 3 DNA or RNA nucleotides which refers to certain amino acid or may also stop the signal at the time of protein synthesis. These are written in a language of four nucleotides. The language of proteins involves 20 amino acids. DNA or RNA is made up of nucleotides such as A, T, G, C, and Uracil in place of thymine in RNA.

Central dogma refers to the flow of genetic information from DNA to RNA and finally leads to protein synthesis. DNA first self-replicates itself and forms a double helical DNA structure which undergoes transcription and forms RNA molecule. The mRNA, rRNA, and tRNA enter the cytoplasm for protein synthesis wherein mRNA is read, rRNA provides ribosomes, and tRNA brings the anticodon for the mRNA strand.

The standard genetic code is known to be represented traditionally as the RNA codon table as when proteins are made in the cell by the aid of ribosomes, it is the mRNA which directs the process of protein synthesis. The mRNA or messenger ribonucleic acid sequence is known to be determined by the sequence of the genomic DNA. TGT and TGC code for cysteine according to the DNA codon table.
