The primary role of mRNA is to:

• process parts of DNA
• transfer parts of DNA to other parts of the cell
• generate vaccines
• unzip the DNA

A main role of rRNA is to:

• translate information in mRNA into protein
• fold polypeptide chains
• read the DNA
• correct problems in the DNA

A key function of tRNA is to:

• retrieve the mRNA
• attach to invading viruses
• carry an amino acid to the ribosome
• break down harmful enzymes

Information coded in the gene is copied into the mRNA in:

• PCR
• translation
• transcription
• none of these

Information in the mRNA is decoded into a chain of amino acids in:

• PCR

• translation

• transcription

• none of these

Which of the following is not an RNA base?
