Protein Synthesis and Mutation

Protein synthesis is split into two main stages. What are they?

• Transformation and transcription
• Transcription and translation
• Transfer and translation
• Transportation and translation

Which of these best summarizes the process of protein synthesis?

• mRNA ---> DNA ---> protein
• DNA ---> mRNA ---> protein
• DNA ---> tRNA ---> protein
• tRNA ---> mRNA ---> protein

An insertion mutation is when

• one or more bases are switched/swapped for another base.
• one or more bases are added into the DNA strand.
• one or more bases are removed from the DNA strand.

An substitution mutation is when

• one or more bases are switched/swapped for another base.

• one or more bases are added into the DNA strand.

• one or more bases are removed from the DNA strand.

A deletion mutation is when

• one or more bases are switched/swapped for another base.

• one or more bases are added into the DNA strand.

• one or more bases are removed from the DNA strand.
