Mutations are random.

• True

• False

Why are insertion and deletion (frameshift) mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence
• They insert things that an organism doesn't need.
• They often delete things that organisms need.
• Insertion and deletions are not any more harmful than substitution mutations.

Where does TRANSCRIPTION occur?

• Nucleus

• Ribosome

• Cytoplasm

• Mitochondria

Why must transcription occur where DNA can be found?

• because DNA can't leave

• because ribosomes are in the nucleus

• because DNA polymerase is found there

• because helicase unzips the DNA

How many codons equals 1 amino acid?

• 1

• 2

• 3

• 4
