A mutation causes a sequence of DNA that has the nucleotides TTG to be changed to TCG. The resulting protein has a different sequence of amino acids.  Which type of mutation is this?

• missense

• nonsense

• silent

• frameshift

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is responsible for the change in the mRNA base?

• silent

• missense

• nonsense

• insertion

Which step in transcription occurs first?

• mRNA moves the code from the nucleus to the ribosome for protein production.

• A gene is expressed through protein production.

• RNA polymerase attaches to the promoter.

• A repressor protein must attach to the operator.

What does DNA provide the code for?

• nitrogenous base pairing

• protein synthesis

• deoxyribose formation

• nucleotide synthesis
