SD8 3.1 Review (2)

What is the primary function of RNA in the cell?

• To store genetic information

• To help make proteins by carrying instructions from DNA to the ribosome

• To replicate DNA

• To break down proteins

What is the process called where a section of DNA is copied into mRNA?

• Translation

• Replication

• Transcription

• Mutation

Which enzyme is responsible for copying a gene from DNA into RNA during transcription?

• DNA Ligase

• RNA Polymerase

• DNA Polymerase

• Helicase

What is the role of mRNA in protein synthesis?

• To carry amino acids to the ribosome

• To take instructions from DNA to the ribosome

• To form the structure of the ribosome

• To catalyze chemical reactions

Where does the process of translation occur in the cell?

• Nucleus

• Mitochondria

• Ribosome

• Golgi apparatus

What happens during the process of translation?

• DNA is copied into RNA

• mRNA is read and amino acids are assembled into a protein

• RNA is converted back into DNA

• Proteins are broken down into amino acids

What is a mutation?

• A process of cell division

• A change in the DNA sequence

• A type of RNA

• A protein synthesis process
