Protein Translation

Although there are a limited number of amino acids, a great variety of proteins are possible because -

• the same amino acid can transform itself.

• the size and configuration of amino acids can vary.

• the sequence and number of amino acids can vary.

• there is a greater number of mRNAs than tRNAs.

tRNA, or _____________ RNA, brings amino acids to the ribosome.

The process of making proteins on the ribosome based on instructions from messenger RNA is called

• transcription

• transformation

• translation

• molecular biology

What best explains the interaction between tRNA and mRNA during translation?

• anticodons on the mRNA line up with complementary codons on the tRNA

• anticodons on the tRNA line up with complementary codons on the mRNA

• tRNA attach amino acids to the complementary mRNA sequence

• mRNA attach amino acids to the complementary tRNA sequence

What do amino acids come together to join?

• a growing polypeptide chain (protein)

• a growing lipid

• a growing carbohydrate

• a growing nucleic acid
