Question

label the diagram. use these choices: transfer rna (trna), amino acid, amino acid chain, codon, anticodon, messenger rna (mrna), ribosome. 20.
21.
22.
23.

1. ribosome

25.
26.
(the diagram shows a translation process with mrna, trna, ribosome, amino acids, and amino acid chain, with labels 20 - 26 to be filled.)

Explanation:

1. 20: The boxed "GLY" is a single building block of the protein chain, so it is an amino acid.
2. 21: The structure carrying the amino acid (GLY) and pairing with mRNA is transfer RNA (tRNA).
3. 22: The 3-nucleotide sequence on mRNA that pairs with tRNA is a codon (here, GGU).
4. 23: The chain of linked amino acids (PHE, GLY, THR, GLY, ARG) is the amino acid chain.
5. 25: The 3-nucleotide sequence on tRNA that pairs with mRNA is an anticodon (here, GGU's complement CCA, or the labeled UGU for another tRNA).
6. 26: The long, linear RNA strand with codons is messenger RNA (mRNA).

(Note: 24 is already labeled as ribosome, which is correct as the structure hosting translation.)

Answer:

1. amino acid
2. transfer RNA (tRNA)
3. codon
4. amino acid chain
5. anticodon
6. messenger RNA (mRNA)
7. (pre-labeled correctly: Ribosome)
