Proteins and DNA

Which of the following is not true about protein synthesis?

• Translation produces a polypeptide from mRNA
• Transcription is the production of mRNA from DNA
• Translation occurs before transcription
• tRNAs read the mRNA and assemble the amino acids

The purpose of nucleic acids like DNA and RNA is to store and pass along

• Water
• Minerals
• Genetic Information
• Energy
