Protein Synthesis

What is the process called that converts the message on mRNA into an amino acid chain?

• Transcription

• Translation

• Replication

• Mutation

How do individual amino acids join together to form proteins?

• Hydrogen bonds

• Ionic bonds

• Peptide bonds

• Covalent bonds

What determines the functionality of a protein?

• Its size and weight

• Its shape and composition

• Its color and texture

• Its temperature and pH

What is the first step in the translation process?

• Ribosome matches tRNA anticodons to mRNA codon sequence

• Ribosome binds to mRNA at a specific area

• Every new tRNA results in an amino acid being added

• End result is a functional protein

What are anticodons?

• 3 bases on mRNA that align to tRNA

• 3 bases on tRNA that align to mRNA

• 3 bases on DNA that align to mRNA

• 3 bases on rRNA that align to tRNA

What happens when a new tRNA enters the ribosome?

• It results in a ribosome binding to mRNA

• It results in a stop sequence being reached

• It results in an amino acid getting added to the chain

• It results in the end of translation

What is the end result of the translation process?

• A new mRNA strand

• A functional protein

• A new DNA strand

• A ribosome

What are the two main processes involved in protein synthesis?

• A) Replication and mutation

• B) Transcription and translation

• C) Translation and replication

• D) Mutation and transcription

What does transcription use to code the message from DNA?

• A) tRNA

• B) rRNA

• C) mRNA

• D) DNA polymerase

During translation, what is used to make proteins?

• A) mRNA

• B) tRNA

• C) DNA

• D) rRNA
