The two kinds of frameshift mutations are:

• Deletion and insertion

• Substitution and silent

A mutation can be passed to offspring only if it takes place in this kind of cell

• skin cell

• gamete cell

• somatic cell

• blood cell

A type of substitution in which no  amino acids change is called 

• Missense
• Nonsense
• Silent
• Deletion

This image show what type of mutation?

• nondisjunction

• frameshift

• gene duplication

• gene translocation

Would a mutation in the DNA of a skin cell be passed on to an organism's offspring?

• Yes, because any change to the DNA is passed on to the offspring
• Maybe. Sex cells only use half of the body's genetic code. It might get the copy of a gene that wasn't mutated.
• No. Only mutations that occur in the gametes (sex cells) are passed on to the offspring
• Without knowing the animal, it would be hard to tell whether or not the mutation would be passed on.

Why is the order of amino acids so important?

• The order of amino acids dictates the function of the protein and what shape the protein will fold into.
• It is not important. The protein folding chamber will force the protein to fold into the correct shape.
• The order of the amino acids tells the cell what DNA to make.
• It is not important that is why most mutatiosn are silent.
