Which type of RNA functions as a blueprint for the genetic code?

• mRNA
• tRNA
• rRNA
• RNA polymerase

What happens during the process of translation?

• The cell uses information from messenger RNA to produce proteins.
• Messenger RNA is made from DNA.
• Copies of DNA molecules are made.
• Transfer RNA is made from messenger RNA.

During translation, the type of amino acid that is added to the growing polypeptide depends on the:

• anticodon on the mRNA only.
• codon on the mRNA only.
• codon on the mRNA and the anticodon on the tRNA to which the amino acid is attached.
• anticodon on the tRNA to which the amino acid is attached only.

In eukaryotes, DNA:

• floats freely in the cytoplasm
• is found in the nucleus
• is wrapped within the ribosome
• is circular

RNA contains the sugar

• ribose
• deoxyribose
• glucose
• lactose

What is the correct amino acid sequence for the mRNA code AUGCCAGUAUGA

• Met-Pro-Ala-Val
• Met-Pro-Val
• Tyr-Gly-His
• Tyr-Gly-Arg-His
