What happens in Inversion?

• Its repeated 
• They all get deleted
• A section of the chromosome gets flipped
• they start to cross-over

What happens in Translocation?

• They all live normaly
• They all repeat each other
• Different chromosomes cross-over with each other
• Something happens

Where do mutations occur?

• DNA and RNA
• DNA 
• RNA
• mRNA and tRNA

What are the building blocks of proteins call?

• DNA
• RNA
• Ribosomes
• Amino Acids

Why are insertion and deletion 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.
