Question

6a. translation adds the correct amino acid for each codon in the ______ molecule.
6b. the amino acid that the ribosome has just added to the growing protein molecule is specified by the uuu codon. write in the abbreviation for this amino acid.
6c. circle a trna molecule.
6d. explain how trna molecules and ribosomes work together to add the correct amino acid for each codon in the mrna molecule.

Explanation:

6a. Translation uses mRNA to build proteins, so the blank is mRNA.
6b. The codon UUU codes for phenylalanine, abbreviated as Phe.
6c. In the diagram, the t - RNA is the clover - shaped structure on the right with an anticodon and an attached amino - acid.
6d. tRNA has an anticodon that is complementary to the mRNA codon. Ribosomes provide the site for the tRNA to bind to the mRNA. When the tRNA's anticodon pairs with the mRNA codon, the amino - acid carried by the tRNA is added to the growing protein chain.

Answer:

6a. mRNA
6b. Phe
6c. (Circle the clover - shaped structure on the right with an anticodon and an attached amino - acid in the diagram)
6d. tRNA anticodons pair with mRNA codons at ribosomes to add amino - acids to the protein chain.
