Match the # in the diagram with the correct structure/term.

Column A Column B
1. _ 1 A. codon
2. _ 2 B. amino acid
3._ 3 C. tRNA (anit-codon)
4._ 4 D. Polypeptide chain (protein)

1 A. amino acid

2 B. Polypeptide chain (protein)

3 C. tRNA (anit-codon)

4 D. codon

Explanation:

The whole diagram explains protein synthesis from transcription to translation.

- The codon, GGU is a codon with a triplet nature coding for glycine, and it consists of three nucleotides

- The amino acid, phenylanine is encoded from the codon, UUU found on the mRNA molecule

- transfer RNA (tRNA) helps to combines covalently with a specific amino acid, threonine and transfers the amino acid to the ribosomes to join the polypeptide chain

- polypeptide chain is a pentapeptide (with five amino acids) and is formed in the final stage of protein synthesis.
